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.
