Installing Sqoop 2

• An operating system supported by CDH 5.
• Oracle JDK.

• Hadoop must be installed on the host that runs the Sqoop 2 server component.

• Services that you want to use with Sqoop, such as HBase, Hive HCatalog, and Accumulo. Sqoop checks for these services when you run it, and finds services that are installed and configured. It logs warnings for services it does not find. These warnings, shown below, are harmless.

  > Warning: /usr/lib/sqoop/../hbase does not exist! HBase imports will fail.
  > Please set $HBASE_HOME to the root of your HBase installation.
  > Warning: /usr/lib/sqoop/../hive-hcatalog does not exist! HCatalog jobs will fail.
  > Please set $HCAT_HOME to the root of your HCatalog installation.
  > Warning: /usr/lib/sqoop/../accumulo does not exist! Accumulo imports will fail.
  > Please set $ACCUMULO_HOME to the root of your Accumulo installation. 

Sqoop 2 is distributed as two separate packages: a client package (sqoop2-client) and a server package (sqoop2-server). Install the server package on one host in the cluster; because the Sqoop 2 server acts as a MapReduce client, this host must have Hadoop installed and configured.

Install the client package on each host that acts as a client. A Sqoop 2 client always connects to the Sqoop 2 server to perform any actions, so Hadoop does not need to be installed on the client hosts.

Depending on what you are planning to install, choose the appropriate package and install it using your preferred package manager application.

To install the Sqoop 2 server package on a RHEL-compatible system:

$ sudo yum install sqoop2-server

To install the Sqoop 2 client package on a RHEL-compatible system:

$ sudo yum install sqoop2-client

To install the Sqoop 2 server package on a SLES system:

$ sudo zypper install sqoop2-server

To install the Sqoop 2 client package on a SLES system:

$ sudo zypper install sqoop2-client

To install the Sqoop 2 server package on an Ubuntu or Debian system:

$ sudo apt-get install sqoop2-server

To install the Sqoop 2 client package on an Ubuntu or Debian system:

$ sudo apt-get install sqoop2-client

You are now ready to configure Sqoop 2. See the next section.
