Flume Installation

Apache Flume is a distributed, reliable, and available system for efficiently collecting, aggregating and moving large amounts of log data from many different sources to a centralized data store.

This guide is for Flume 1.x (specifically the 1.3.0 release).
  Note:

If you are looking for Flume 0.9.x:

For information on Flume 0.9.x, see the Flume 0.9.x documentation. To install Flume 0.9.x instead of Flume 1.x, go to http://archive.cloudera.com/cdh4-deprecated.

You cannot install both Flume 0.9.x and Flume 1.x together on the same host.
