Description

In rsgroup, allow to move tables that do not exist. This can cause dirty data.

base(main):004:0* move_rsgroup_tables 'rs1',['ttt']

hbase(main):005:0> get_rsgroup 'rs1'
GROUP INFORMATION 
Servers: 
192.168.12.65:16020  
Tables: 
ttt 

 
I think it should be like this. As follows:

hbase(main):001:0> move_rsgroup_tables 'rs1',['ttt']

ERROR: org.apache.hadoop.hbase.constraint.ConstraintException: Source group is null for table ttt ,table must exist.

Here is some help for this command:
Reassign tables from one group to another.

  hbase> move_rsgroup_tables 'dest',['table1','table2']
