------------------------------------

             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 (org.apache.avro.ipc.NettyServer$NettyServerAvroHandler.exceptionCaught:201) - Unexpected exception from downstream.

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
