Reuse compression streams in HFileBlock.Writer
----------------------------------------------
Key: HBASE-5387
URL: https://issues.apache.org/jira/browse/HBASE-5387
Project: HBase
Issue Type: Bug
Reporter: Mikhail Bautin
We need to to reuse compression streams in HFileBlock.Writer instead of
allocating them every time. The motivation is that when using Java's built-in
implementation of Gzip, we allocate a new GZIPOutputStream object and an
associated native data structure any time. This is one suspected cause of
recent TestHFileBlock failures on Hadoop QA:
