Subject [jira] [Created] (HBASE-5387) Reuse compression streams in HFileBlock.Writer
Date Sat, 11 Feb 2012 02:47:00 GMT
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: https://builds.apache.org/job/HBase-TRUNK/2658/testReport/org.apache.hadoop.hbase.io.hfile/TestHFileBlock/testPreviousOffset_1_/.
