Subject Re: flume restart exception
Date Thu, 18 Oct 2012 16:48:32 GMT
Raymond, 

This was an issue which we fixed (FLUME-1380) and will be part of Flume-1.3.0. If you need
it immediately, you could clone trunk/flume-1.3.0 branch and build it. You should not see
this error once you do that. Or you can wait for the next release - Flume-1.3.0, which should
be released in the next few weeks or so.


Thanks
Hari
