Subject [jira] [Commented] (HIVE-13354) Add ability to specify Compaction options per table and per request
Date Wed, 25 May 2016 06:09:13 GMT


Wei Zheng commented on HIVE-13354:

The only failure that looks related is TestTxnCommands.testSimpleAcidInsert. But this one
doesn't fail local to me.

[~ekoifman] Can you take a look at patch 2?

> 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
> 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
