> 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)
