qgxiaozhan updated HBASE-16222:
-------------------------------
    Affects Version/s: 2.0.0
                       1.2.2
          Description: 
RegionServer Host Name was not equa meta table'r regionserver hostName.
For example, host BeiJIN.98.100.hbase.com In zk or master is 
beijin.98.100.hbase.com , but in meter table  is BeiJIN.98.199.hbase.com. 
Because of this , when rsgroup balance compare host , that cause problem .The 
reason  is  when regionserver report host to master , it will make the hostname 
to lowcase。

  was:
I migrated rs-group in 1.1.2version,and found regionserver host is different 
between zk and meta table. 
For example, host BeiJIN.98.100.hbase.com In zk or master is 
beijin.98.100.hbase.com , but in meter table  is BeiJIN.98.199.hbase.com. 
Because of this , when rsgroup balance compare host , that cause problem 。 
And i found when regionserver report host to master , it will make the hostname 
to lowcase。
