2. Install Flume

Flume is included in the HDP repository, but it is not installed automatically as part of the standard HDP installation process.

The following Flume components have HDP component dependencies. You cannot use these Flume components if the dependencies are not installed.

Table 13.1. Flume 1.4.0 Dependencies
Flume 1.4.0 Component HDP Component Dependencies
HDFS Sink Hadoop 2.2.0
HBase Sink HBase 0.96.1

See HDP Deployment Options for more information.
Verify the HDP repositories are available:
yum list flume
The output should list at least one Flume package similar to the following:
flume.noarch 1.5.2.2.2.6.0-2800.el6 HDP-2.2
If yum responds with "Error: No matching package to list" as shown below, yum cannot locate a matching RPM. This can happen if the repository hosting the HDP RPMs is unavailable, or has been disabled. Follow the instructions at Configure the Remote Repositories to configure either a public or private repository before proceeding.
Error: No matching package to list.
You must correctly set and export your JAVA_HOME environment variable for your operating system. See JDK Requirements for instructions on installing JDK.

Flume 1.4.0 Component	HDP Component Dependencies
