Cesar Delgado created FLUME-2370:
------------------------------------
Summary: 'deflate' doesn't work in Flume avro sinc/source
Key: FLUME-2370
URL: https://issues.apache.org/jira/browse/FLUME-2370
Project: Flume
Issue Type: Documentation
Components: Docs
Affects Versions: v1.4.0
Reporter: Cesar Delgado
I was trying to setup a basic 2-tier Flume setup using the Avro source/sink to
communicate between tiers. When I setup the system I used compression-type on
the 1st tier's sink side like documented here
(https://flume.apache.org/FlumeUserGuide.html#avro-sink)
agent.sinks.snk1.compression-type = deflate
And the same on the source side:
agent.sources.src1.compression-type = deflate
But I was getting this error:
08 Apr 2014 00:15:07,606 WARN pool-7-thread-1

After some digging I found if I changed 'deflate' for 'gzip' it works.
agent.sinks.snk1.compression-type = gzip
agent.sources.src1.compression-type = gzip
