    Description

      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
