Subject [jira] [Created] (HIVE-2318) Support multiple file systems

Support multiple file systems
-----------------------------

                 Key: HIVE-2318
                 URL: https://issues.apache.org/jira/browse/HIVE-2318
             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.
