--------------------------------------------
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}}
