Flume 1.x provides a template configuration file for flume.conf called conf/flume-conf.properties.template and a template for flume-env.sh called conf/flume-env.sh.template.

1. Copy the Flume template property file conf/flume-conf.properties.template to conf/flume.conf, then edit it as appropriate.

   $ sudo cp conf/flume-conf.properties.template conf/flume.conf

   This is where you define your sources, sinks, and channels, and the flow within an agent. By default, the properties file is configured to work out of the box using a sequence generator source, a logger sink, and a memory channel. For information on configuring agent flows in Flume 1.x, as well as more details about the supported sources, sinks and channels, see the documents listed under Viewing the Flume Documentation.

2. Optionally, copy the template flume-env.sh file conf/flume-env.sh.template to conf/flume-env.sh.

   $ sudo cp conf/flume-env.sh.template conf/flume-env.sh

   The flume-ng executable looks for a file named flume-env.sh in the conf directory, and sources it if it finds it. Some use cases for using flume-env.sh are to specify a bigger heap size for the Flume agent, or to specify debugging or profiling options using JAVA_OPTS when developing your own custom Flume NG components, such as sources and sinks. If you do not make any changes to this file, then you need not perform the copy as it is empty by default.
