> OutOfMemoryError in HDFSSink
> ----------------------------
>
> Key: FLUME-1326
> URL: https://issues.apache.org/jira/browse/FLUME-1326
> Project: Flume
> Issue Type: Bug
> Affects Versions: v1.2.0
> Reporter: Juhani Connolly
> Priority: Critical
>
> We run a 3 node/1 collector test cluster pushing about 350events/sec per node... Not really high stress, but just something to evaluate flume with.
> Consistently our collector has been dying because of an OOMError killing the SinkRunner after running for about 30-40 hours(seems pretty consistent as we've had it 3 times now).
> Suspected cause would be a memory leak somewhere in HdfsSink. The feeder nodes which run AvroSink instead of HdfsSink have been up and running for about a week without restarts.
