> 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
