Cloudera Enterprise 5.15.x | Other versions

Installing the Latest CDH 5 Release

This page explains how to do an unmanaged deployment of CDH 5 from the command line. For a managed deployment, see Cloudera Manager Deployment.

CDH 5 Installation Options

There are multiple ways to install CDH 5:

  • Managed Deployment: automatically install CDH 5 with a Cloudera Manager Deployment. This is the simplest and preferred method.
  • Unmanaged Deployment:
    • Manually install the CDH 5 package or repository: either add the CDH 5 repository OR build your own CDH 5 repository.
    • Manually install the CDH 5 tarball. See "Package and Tarball Binaries" below.
  Note: Cloudera recommends installing CDH 5 and dependencies with Cloudera Manager.

Package and Tarball Binaries

Installing from Packages

Installing from a Tarball

  • The CDH 5 tarball deploys YARN and includes the MRv1 binaries. There is no separate tarball for MRv1. The MRv1 scripts are in the directory, bin-mapreduce1, and examples are in examples-mapreduce1.

Before You Begin Installing CDH 5 Manually

  Note: Running Services

Use the service command to start, stop, and restart CDH components, instead of running scripts in /etc/init.d directly. The service command creates a predictable environment by setting the current working directory to / and removing most environment variables (passing only LANG and TERM). With /etc/init.d, existing environment variables remain in force and can produce unpredictable results. When you install CDH from packages, service is installed as part of the Linux Standard Base (LSB).

Steps to Install CDH 5 Manually

Step 1: Add or Build the CDH 5 Repository

  • To install CDH 5 on a RHEL system, download packages with yum or use a web browser.
  • To install CDH 5 on a SLES system, download packages with zypper or YaST or use a web browser.
  • To install CDH 5 on an Ubuntu or Debian system, download packages with apt or use a web browser.

On RHEL-compatible Systems

Use one of the following methods to install CDH 5 on RHEL-compatible systems.

Do this on all the systems in the cluster.

To add the CDH 5 repository:

Download the repo file. Click the link for your RHEL or CentOS system in the table, find the appropriate repo file, and save in /etc/yum.repos.d/.

For OS Version

  • Download the appropriate repo file
  • Create the repo
  • Distribute the repo and set up a web server.

Continue with Step 2: Optionally Add a Repository Key. Then choose Step 3: Install CDH 5 with YARN, or Step 4: Install CDH 5 with MRv1; or do both steps to install both implementations.

  Note: Clean repository cache.
Before proceeding, clean cached packages and headers to ensure your system repos are up-to-date: 
sudo yum clean all

On SLES Systems

Use one of the following methods to download the CDH 5 repository or package on SLES systems.

To add the CDH 5 repository:

  1. Run the following command: 
    $ sudo zypper addrepo -f https://archive.cloudera.com/cdh5/sles/12/x86_64/cdh/cloudera-cdh.repo
  2. Update your system package index by running: 
    $ sudo zypper refresh

Continue with Step 2: Optionally Add a Repository Key. Then choose Step 3: Install CDH 5 with YARN, or Step 4: Install CDH 5 with MRv1; or do both steps to install both implementations.

  Note: Clean repository cache.
Before proceeding, clean cached packages and headers to ensure your system repos are up-to-date: 
sudo zypper clean --all

OR: To build a SLES repository:

If you want to create your own SLES repository, create a mirror of the CDH SLES directory by following these instructions that explain how to create a SLES repository from the mirror.

Continue with Step 2: Optionally Add a Repository Key. Then choose Step 3: Install CDH 5 with YARN, or Step 4: Install CDH 5 with MRv1; or do both steps to install both implementations.

  Note: Clean repository cache.
Before proceeding, clean cached packages and headers to ensure your system repos are up-to-date: 
sudo zypper clean --all

On Ubuntu or Debian Systems

Use one of the following methods to download the CDH 5 repository or package.

To add the CDH 5 repository:

  • Download the appropriate cloudera.list file by issuing one of the following commands. You can use another HTTP client if wget is not available, but the syntax may be different.
      Important: Ubuntu 14.04 (Trusty)

    For Ubuntu Trusty systems, you must perform an extra step after adding the repository. See "Additional Step for Trusty Ubuntu Trusty and Debian Jessie" below.

    OS Version Command
    Debian 8 Jessie 
    $ sudo wget 'https://archive.cloudera.com/cdh5/debian/jessie/amd64/cdh/cloudera.list' \
    -O /etc/apt/sources.list.d/cloudera.list
    Debian 7 Wheezy 
    $ sudo wget 'https://archive.cloudera.com/cdh5/debian/wheezy/amd64/cdh/cloudera.list' \
    -O /etc/apt/sources.list.d/cloudera.list
    Ubuntu 16 Xenial 
    $ sudo wget 'https://archive.cloudera.com/cdh5/ubuntu/xenial/amd64/cdh/cloudera.list' \
    -O /etc/apt/sources.list.d/cloudera.list
    Ubuntu 14 Trusty 
    $ sudo wget 'https://archive.cloudera.com/cdh5/ubuntu/trusty/amd64/cdh/cloudera.list' \
    -O /etc/apt/sources.list.d/cloudera.list
    Ubuntu 12 Precise 
    $ sudo wget 'https://archive.cloudera.com/cdh5/ubuntu/precise/amd64/cdh/cloudera.list' \
    -O /etc/apt/sources.list.d/cloudera.list
  Note: Clean repository cache.
Before proceeding, clean cached packages and headers to ensure your system repos are up-to-date: 
sudo apt-get update
Additional step for Ubuntu Trusty and Debian Jessie

This step ensures that you get the right ZooKeeper package for the current CDH release. You need to prioritize the Cloudera repository you have just added, such that you install the CDH version of ZooKeeper rather than the version that is bundled with Ubuntu Trusty or Debian Jessie.

To do this, create a file at /etc/apt/preferences.d/cloudera.pref with the following contents: 
Package: *
Pin: release o=Cloudera, l=Cloudera
Pin-Priority: 501
  Note: You do not need to run apt-get update after creating this file.

Continue with Step 2: Optionally Add a Repository Key. Then choose Step 3: Install CDH 5 with YARN, or Step 4: Install CDH 5 with MRv1; or do both steps to install both implementations.

OR: To build a Debian repository:

If you want to create your own apt repository, create a mirror of the CDH Debian directory and then create an apt repository from the mirror.

Continue with Step 2: Optionally Add a Repository Key. Then choose Step 3: Install CDH 5 with YARN, or Step 4: Install CDH 5 with MRv1; or do both steps to install both implementations.

Step 2: Optionally Add a Repository Key

Before installing YARN or MRv1: (Optionally) add a repository key on each system in the cluster. Add the Cloudera Public GPG Key to your repository by executing one of the following commands:

  • For RHEL/CentOS/Oracle 5 systems: 
    sudo rpm --import https://archive.cloudera.com/cdh5/redhat/5/x86_64/cdh/RPM-GPG-KEY-cloudera
  • For RHEL/CentOS/Oracle 6 systems: 
    sudo rpm --import https://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/RPM-GPG-KEY-cloudera
  • For RHEL/CentOS/Oracle 7 systems: 
    sudo rpm --import https://archive.cloudera.com/cdh5/redhat/7/x86_64/cdh/RPM-GPG-KEY-cloudera
  • For all SLES systems: 
    sudo rpm --import https://archive.cloudera.com/cdh5/sles/12/x86_64/cdh/RPM-GPG-KEY-cloudera
  • For Ubuntu or Debian systems:
    OS Version Command
    Debian 8 Jessie 
    $ wget https://archive.cloudera.com/cdh5/debian/jessie/amd64/cdh/archive.key -O archive.key
$ sudo apt-key add archive.key
    Debian 7 Wheezy 
    $ wget https://archive.cloudera.com/cdh5/debian/wheezy/amd64/cdh/archive.key -O archive.key
$ sudo apt-key add archive.key
    Ubuntu 16 Xenial 
    $ wget https://archive.cloudera.com/cdh5/ubuntu/xenial/amd64/cdh/archive.key -O archive.key
$ sudo apt-key add archive.key
    Ubuntu 14 Trusty 
    $ wget https://archive.cloudera.com/cdh5/ubuntu/trusty/amd64/cdh/archive.key -O archive.key
$ sudo apt-key add archive.key
    Ubuntu 12 Precise 
    $ wget https://archive.cloudera.com/cdh5/ubuntu/precise/amd64/cdh/archive.key -O archive.key
$ sudo apt-key add archive.key

This key enables you to verify that you are downloading genuine packages.

Step 3: Install CDH 5 with YARN

  Note: Skip this step if you intend to use only MRv1. Directions for installing MRv1 are in Step 4.

To install CDH 5 with YARN:

  Note: When configuring HA for the NameNode, do not install hadoop-hdfs-secondarynamenode. After completing the HA software configuration, follow the installation instructions under Deploying HDFS High Availability.
  1. Install and deploy ZooKeeper.
      Important: Cloudera recommends that you install (or update) and start a ZooKeeper cluster before proceeding. This is a requirement if you are deploying high availability (HA) for the NameNode.

    Follow instructions under ZooKeeper Installation.

  2. Install each type of daemon package on the appropriate systems(s), as follows.

    Where to install

    Install commands

    Resource Manager host (analogous to MRv1 JobTracker) running:

     

    RHEL/CentOS compatible

    sudo yum clean all; sudo yum install hadoop-yarn-resourcemanager

    SLES

    sudo zypper clean --all; sudo zypper install hadoop-yarn-resourcemanager

    Ubuntu or Debian

    sudo apt-get update; sudo apt-get install hadoop-yarn-resourcemanager

    NameNode host running:

     

    RHEL/CentOS compatible

    sudo yum clean all; sudo yum install hadoop-hdfs-namenode

    SLES

    sudo zypper clean --all; sudo zypper install hadoop-hdfs-namenode

    Ubuntu or Debian

    sudo apt-get install hadoop-hdfs-namenode

    Secondary NameNode host (if used) running:

     

    RHEL/CentOS compatible

    sudo yum clean all; sudo yum install hadoop-hdfs-secondarynamenode

    SLES

    sudo zypper clean --all; sudo zypper install hadoop-hdfs-secondarynamenode

    Ubuntu or Debian

    sudo apt-get install hadoop-hdfs-secondarynamenode

    All cluster hosts except the Resource Manager running:

     

    RHEL/CentOS compatible

    sudo yum clean all; sudo yum install hadoop-yarn-nodemanager hadoop-hdfs-datanode hadoop-mapreduce

    SLES

    sudo zypper clean --all; sudo zypper install hadoop-yarn-nodemanager hadoop-hdfs-datanode hadoop-mapreduce

    Ubuntu or Debian

    sudo apt-get install hadoop-yarn-nodemanager hadoop-hdfs-datanode hadoop-mapreduce

    One host in the cluster running:

     

    RHEL/CentOS compatible

    sudo yum clean all; sudo yum install hadoop-mapreduce-historyserver hadoop-yarn-proxyserver

    SLES

    sudo zypper clean --all; sudo zypper install hadoop-mapreduce-historyserver hadoop-yarn-proxyserver

    Ubuntu or Debian

    sudo apt-get install hadoop-mapreduce-historyserver hadoop-yarn-proxyserver

    All client hosts running:

     

    RHEL/CentOS compatible

    sudo yum clean all; sudo yum install hadoop-client

    SLES

    sudo zypper clean --all; sudo zypper install hadoop-client

    Ubuntu or Debian

    sudo apt-get install hadoop-client
  Note: The hadoop-yarn and hadoop-hdfs packages are installed on each system automatically as dependencies of the other packages.

Step 4: Install CDH 5 with MRv1

  Note: If installing both MRv1 and YARN, do not install packages that you already installed in Step 3: Install CDH 5 with YARN. If installing YARN only, skip this step and go to Step 3: Install CDH 5 with YARN.
  Important: Before proceeding, you need to decide:
  • Whether to configure High Availability (HA) for the NameNode or JobTracker; see the High Availability for more information and instructions.
  • Where to deploy the NameNode, Secondary NameNode, and JobTracker daemons. As a general rule:
    • The NameNode and JobTracker run on the same "master" host unless the cluster is large (more than a few tens of nodes), and the master host (or hosts) should not run the Secondary NameNode (if used), DataNode or TaskTracker services.
    • In a large cluster, it is especially important that the Secondary NameNode (if used) runs on a separate machine from the NameNode.
    • Each node in the cluster except the master host(s) should run the DataNode and TaskTracker services.

If you decide to configure HA for the NameNode, do not install hadoop-hdfs-secondarynamenode. After completing the HA software configuration, follow the installation instructions under Deploying HDFS High Availability.

First, install and deploy ZooKeeper.
  Important: Cloudera recommends that you install (or update) and start a ZooKeeper cluster before proceeding. This is a requirement if you are deploying high availability (HA) for the NameNode or JobTracker.

Follow instructions under ZooKeeper Installation. Make sure you create the myid file in the data directory, as instructed, if you are starting a ZooKeeper ensemble after a fresh install.

Next, install packages.

Install each type of daemon package on the appropriate systems(s), as follows.
  Note: Ubuntu systems may try to start the service immediately after you install it. This should fail harmlessly, but you can find information at askubuntu on how to prevent this.

Step 5: (Optional) Install LZO

This section explains how to install LZO ( Lempel–Ziv–Oberhumer) compression. For more information, see Choosing and Configuring Data Compression
  Note: If upgrading (rather than installing for the first time), remove the old LZO version first. For example, on a RHEL system: 
yum remove hadoop-lzo
  1. Add the repository on each host in the cluster. Follow the instructions for your OS version:
    For OS Version Do this
    RHEL/CentOS/Oracle 5 Go to this link and save the file in the /etc/yum.repos.d/ directory.
    RHEL/CentOS/Oracle 6 Go to this link and save the file in the /etc/yum.repos.d/ directory.
    RHEL/CentOS/Oracle 7 Go to this link and save the file in the /etc/yum.repos.d/ directory.
    SLES
    1. Run the following command: 
       $ sudo zypper addrepo -f
https://archive.cloudera.com/gplextras5/sles/12/x86_64/gplextras/
cloudera-gplextras5.repo
    2. Update your system package index by running: 
       $ sudo zypper refresh
    Ubuntu or Debian Go to this link and save the file as /etc/apt/sources.list.d/gplextras.list.
      Important: Make sure you do not let the file name default to cloudera.list, as that will overwrite your existing cloudera.list.
  2. Install the package on each host as follows:
    For OS version Install commands
    RHEL/CentOS compatible 
    sudo yum install hadoop-lzo
    SLES 
    sudo zypper install hadoop-lzo
    Ubuntu or Debian 
    sudo apt-get install hadoop-lzo
  3. Continue with installing and deploying CDH. As part of the deployment, you will need to do some additional configuration for LZO, as shown under Configuring LZO.
      Important: Be sure to do this configuration after you have copied the default configuration files to a custom location and set alternatives to point to it.

Step 6: Deploy CDH and Install Components
