--------------------------------------------

Hi Mithun, thanks for the providing the patch. Can you please update the patch with HIVE specific
JIRA number and description of this JIRA as per our convention? You can add a line in the
description where this patch was cherry-picked from I you like.. Also, wondering how the patch
alleviates the problem? If there are hundreds of partitions being added, aren't they already
in memory in the {{List<Partition> parts}} object? If you have any stats to share it
would be great. Eg. before --> running out of memory at X number of partitions ; after
--> running out of memory at X+Y number of partitions. Thanks!

> For large batches (e.g. hundreds) of {{addPartitions()}}, the {{ObjectStore}} runs out
of memory. Flushing the {{PersistenceManager}} alleviates the problem.
