Re: error writing to collectorSink on mac os x

Ah, got it.

You are use flume 0.9.x - which is a pretty old version. We're on FlumeNG - actually Flume 1.2.0, but 1.3.0 will be released very soon. I strongly suggest to move over, since 0.9.x will not get so much attention ;)

For Flume 1.2. please check:
https://cwiki.apache.org/confluence/display/FLUME/Home

UserGuide:
http://flume.apache.org/FlumeUserGuide.html

And a tip beside - please don't use homebrew for hadoop related projects. They all can be build natively on OSX :)

cheers,
 Alex
