HI Arvind,
Yeah i have done the same and able to integrate a custom sink with Flume. I think there has to be some extender facility in Flume, so that i don't have to make any code changes in Flume. i have tried the other way around i.e. copying the jar file in the lib directory, but it didn't work.

Hi Som,

Look at the implementation of NullSink to get an idea of how to code
up the sink. Once it is ready, make sure that you have it packaged in
the lib directory of the distribution and reference it by using the
fully qualified class name of the implementation in  the type
