Vihang Karajgaonkar commented on HIVE-17188:
--------------------------------------------
Yes, would probably make sense to merge this in branch-2.3 as well if this is
available in 2.2.0 release. Otherwise, this patch would be available in 2.2.0
and 2.4.0 but not in 2.3.0
> ObjectStore runs out of memory for large batches of addPartitions().

> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 2.2.0
> Reporter: Mithun Radhakrishnan
> Assignee: Chris Drome
> Fix For: 2.2.0, 3.0.0

> Attachments: HIVE-17188.1.patch
>
>
> 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].)
