Subject Re: what are the libraries needed for flume log4jappender
Date Wed, 23 Jan 2013 21:39:27 GMT
Arvind,

Thanks for the information, is there any dependency walker tool or do we
have to do this manually?
I have gone thru the pom.xml, which lists junit and others also as
dependency, so how to avoid some of them which are unnecessary.
