>                 URL:
>             Project: Hive
>          Issue Type: New Feature
>            Reporter: Vaibhav Aggarwal
>            Assignee: Vaibhav Aggarwal
> Currently some of the Hive tasks like MoveTask, ConditionalMergeResolver assume that
the data is being copied or moved on the same file system.
> These operators file if the source table is in one filesystem (like HDFS) and destination
table is in another file system (like s3).
> This patch aims at:
> 1. Support moving data between different file systems.
> 2. Add support for file systems which do not support 'move' operation like s3.
> 3. Remove redundant operations like moving data from and to the same location.
