Subject [jira] [Created] (HIVE-3153) Release codecs and output streams between flushes of RCFile

Owen O'Malley created HIVE-3153:
-----------------------------------

             Summary: Release codecs and output streams between flushes of RCFile
                 Key: HIVE-3153
                 URL: https://issues.apache.org/jira/browse/HIVE-3153
             Project: Hive
          Issue Type: Improvement
          Components: Compression
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


Currently, RCFile writer holds a compression codec per a file and a compression output stream
per a column. Especially for queries that use dynamic partitions this quickly consumes a lot
of memory.

I'd like flushRecords to get a codec from the pool and create the compression output stream
in flushRecords.
