Mithun Radhakrishnan commented on HIVE-17188:
---------------------------------------------

I'm +1 on this change. This has been running in production for some time now. 

I'd like to commit this to {{master}} and {{branch-2}}, tomorrow, unless there 
is objection.

> ObjectStore runs out of memory for large batches of addPartitions().

>
> For large batches (e.g. hundreds) of {{addPartitions()}}, the {{ObjectStore}} 
> runs out of memory. Flushing the {{PersistenceManager}} alleviates the 
> problem.
> Note: The problem being addressed here isn't so much with the size of the 
> hundreds of Partition objects, but the cruft that builds with the 
> PersistenceManager, in the JDO layer, as confirmed through memory-profiling.
> (Raising this on behalf of [~cdrome] and [~thiruvel].)
