> Key: HIVE-7389
> URL: https://issues.apache.org/jira/browse/HIVE-7389
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.14.0
> Reporter: Rajesh Balamohan
> Labels: performance
> Attachments: HIVE-7389.1.patch, local_vm_testcase.txt

>
> When the number of dynamic partitions to be loaded are high, the time taken
> for 'MoveTask' is greater than the actual job in some scenarios. It would be
> possible to reduce overall runtime by reducing the number of calls made to
> metastore from MoveTask operation.
