separate compression options for different output types
-------------------------------------------------------
Key: HIVE-85
URL: https://issues.apache.org/jira/browse/HIVE-85
Project: Hadoop Hive
Issue Type: Bug
Reporter: Joydeep Sen Sarma
currently hive uses mapred.output.compress to determine compression for all
output files. however not all files are final output. at least three different
kinds of output files are generated:
1. intermediate output files for next map-reduce job
2. files targeted for result hdfs directories or hive tables/partitions (which
are just hdfs dirs)
3. files written to user local directories (downloading results)
the plan is to provide three separate options for controlling 1,2,3 separately.
we may want to split (2) in case compression is determined by table metadata
(and not session options).
