Subject [jira] [Created] (HIVE-13354) Add ability to specify Compaction options per table
Date Thu, 24 Mar 2016 17:16:25 GMT
Eugene Koifman created HIVE-13354:

             Summary: Add ability to specify Compaction options per table
                 Key: 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
