Subject Re: what are the libraries needed for flume log4jappender
Date Wed, 23 Jan 2013 20:24:07 GMT
Mike,

When I include all the libraries it is not giving compilation problem, but
log4jappender documentation says it only needs flume-ng-sdk.jar file.

In that case, if I want to ship flume log4jappender, should I have to ship
all these jar files in flume/lib directory?
