             Summary: Use CodecPool in compressed stream to prevent leak of 
direct buffers
                 Key: FLUME-2416
                 URL: https://issues.apache.org/jira/browse/FLUME-2416
             Project: Flume
          Issue Type: Bug
            Reporter: Hari Shreedharan
            Assignee: Hari Shreedharan
         Attachments: FLUME-2416.patch

Even though they may no longer be references, Java only cleans up direct 
buffers on full gc. If there is enough heap available, a full GC is never hit 
and these buffers are leaked. Hadoop keeps creating new compressors instead of 
using the pools causing a leak - which is a bug in itself which is being 
addressed by HADOOP-10591
