-------------------------------------
Summary: Add ability to specify Compaction options per table
Key: HIVE-13354
URL: https://issues.apache.org/jira/browse/HIVE-13354
Project: Hive
Issue Type: Improvement
Affects Versions: 2.0.0, 1.3.0
Reporter: Eugene Koifman
Assignee: Eugene Koifman
Currently the are a few options that determine when automatic compaction is
triggered. They are specified once for the warehouse.
This doesn't make sense - some table may be more important and need to be
compacted more often.
We should allow specifying these on per table basis.
Also, compaction is an MR job launched from within the metastore. There is
currently no way to control job parameters (like memory, for example) except to
specify it in hive-site.xml for metastore which means they are site wide.
Should add a way to specify these per table (perhaps even per compaction if
launched via ALTER TABLE)
