> 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: https://builds.apache.org/job/HBase-TRUNK/2658/testReport/org.apache.hadoop.hbase.io.hfile/TestHFileBlock/testPreviousOffset_1_/.
