             Summary: [RSGROUP] Add shell command to move servers and tables at the same time
                 Key: HBASE-17758
                 URL: https://issues.apache.org/jira/browse/HBASE-17758
             Project: HBase
          Issue Type: New Feature
          Components: rsgroup
            Reporter: Guangxu Cheng


Currently add a new group perform the following steps:
{code:javascript}
hbase(main):001:0> add_rsgroup 'mygroup'
Took 0.3840 seconds
hbase(main):002:0> move_servers_rsgroup 'mygroup',['hbase-rs-01:16030','hbase-rs-02:16030']
Took 3.5040 seconds
hbase(main):003:0> move_tables_rsgroup 'mygroup',['example']
Took 0.2710 seconds
{code}
1. move_servers_rsgroup will unassign all regions on hbase-rs-01 and hbase-rs-02
2. move_tables_rsgroup will also reassign all the regions of the table example.

This will lead to a large number of regions to migrate and affect the data locality.

However, some regions of the table that are distributed on hbase-rs-01 and hbase-rs-02, do not need to be moved.

So,we need a new shell command *move_servers_tables_rsgroup*.
