9.1. Validate Flume

By default on installation Flume does not start running immediately. To validate, replace your default conf/flume.conf with the provdied flume.conf, restart flume, and see if the data is flowing by examining the destination.

Use this flume.conf file:

                1. Name the components on this agent
                   a1.sources = r1 
                   a1.sinks = k1 
                   a1.channels = c1
                2.Describe/configure the source
                   a1.sources.r1.type = seq
                3. Describe the sink
                   a1.sinks.k1.type = file_roll 
                   a1.sinks.k1.channel = c1 
                   a1.sinks.k1.sink.directory = /tmp/flume
                4. Use a channel which buffers events in memory
                   a1.channels.c1.type = memory
                5. Bind the source and sink to the channel
                   a1.sources.r1.channels = c1 
                   a1.sinks.k1.channel = c1

After starting flume, check /tmp/flume to see if there are any files there. The files should contain simple sequential numbers. After validating, stop flume and revert changes to flume.conf to prevent your disk from filling up.
