Steps to Install CDH 5 Manually

CDH 5 Installation Options

There are multiple ways to install CDH 5:

Automatically install CDH 5 with a Cloudera Manager Deployment. This is the simplest and preferred method.
Manually install the CDH 5 package or repository in one of three ways:
- Install the CDH 5 "1-click" package (preferred manual method) OR
- Add the CDH 5 repository OR
- Build your own CDH 5 repository.
Manually install the CDH 5 tarball. See "Package and Tarball Binaries" below.

Package and Tarball Binaries

Installing from Packages

To install and deploy YARN, see Deploying MapReduce v2 (YARN) on a Cluster.
To install and deploy MRv1, see Deploying MapReduce v1 (MRv1) on a Cluster.

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

To migrate from MRv1 to YARN, see Migrating from MapReduce (MRv1) to MapReduce (MRv2).
For a list of supported operating systems, see CDH 5 Requirements and Supported Versions.
Installing CDH 5 requires sudo privileges. If necessary, use root user (superuser) to configure sudo privileges.
CDH5 requires the Oracle Java Development Kit (JDK). See Java Development Kit Installation.
In CDH 5, both the NameNode and Resource Manager (or Job Tracker) can be configured for High Availability
Use the service (8) command to start and stop services rather than running scripts in /etc/init.d directly.

Additional step for Trusty

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.

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

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/11/x86_64/cdh/RPM-GPG-KEY-cloudera

For Ubuntu or Debian systems:

OS Version	Command
Debian Wheezy	$ wget https://archive.cloudera.com/cdh5/debian/wheezy/amd64/cdh/archive.key -O archive.key $ sudo apt-key add archive.key
Ubuntu Precise	$ wget https://archive.cloudera.com/cdh5/ubuntu/precise/amd64/cdh/archive.key -O archive.key $ sudo apt-key add archive.key
Ubuntu Lucid	$ wget https://archive.cloudera.com/cdh5/ubuntu/lucid/amd64/cdh/archive.key -O archive.key $ sudo apt-key add archive.key
Ubuntu Trusty	$ wget https://archive.cloudera.com/cdh5/ubuntu/trusty/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

To install CDH 5 with YARN:

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.

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`

Step 4: Install CDH 5 with MRv1

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.

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.

Where to install	Install commands
JobTracker host running:
RHEL/CentOS compatible	`sudo yum clean all; sudo yum install hadoop-0.20-mapreduce-jobtracker`
SLES	`sudo zypper clean --all; sudo zypper install hadoop-0.20-mapreduce-jobtracker`
Ubuntu or Debian	`sudo apt-get update; sudo apt-get install hadoop-0.20-mapreduce-jobtracker`
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 JobTracker, NameNode, and Secondary (or Standby) NameNode hosts running:
RHEL/CentOS compatible	`sudo yum clean all; sudo yum install hadoop-0.20-mapreduce-tasktracker hadoop-hdfs-datanode`
SLES	`sudo zypper clean --all; sudo zypper install hadoop-0.20-mapreduce-tasktracker hadoop-hdfs-datanode`
Ubuntu or Debian	`sudo apt-get install hadoop-0.20-mapreduce-tasktracker hadoop-hdfs-datanode`
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`

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

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	Run the following command: $ sudo zypper addrepo -f https://archive.cloudera.com/gplextras5/sles/11/x86_64/gplextras/ cloudera-gplextras5.repo 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.

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
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.

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

Step 6: Deploy CDH and Install Components

Proceed with:

Creating a Local Yum Repository
