----------------------------------

             Summary: Interactions in RSGroup test classes will cause TestRSGroupsAdmin2.testMoveServersAndTables and TestRSGroupsBalance.testGroupBalance flaky  
                 Key: HBASE-22424
                 URL: https://issues.apache.org/jira/browse/HBASE-22424
             Project: HBase
          Issue Type: Bug
          Components: rsgroup
    Affects Versions: 2.2.0
            Reporter: Xiaolin Ha
            Assignee: Xiaolin Ha


When running rsgroup test class folder to run all the UTs together, TestRSGroupsAdmin2.testMoveServersAndTables and TestRSGroupsBalance.testGroupBalance will flaky.
Because TestRSGroupsAdmin1, TestRSGroupsAdmin2 and TestRSGroupsBalance are all extends TestRSGroupsBase, which has a static variable INIT, controlling the initialize of 'master 'group and the number of rs in 'default' rsgroup. 

Output errors of TestRSGroupsBalance.testGroupBalance is shown in HBASE-22420, and  TestRSGroupsAdmin2.testMoveServersAndTables will encounter NPE in ```rsGroupAdmin.getRSGroupInfo("master").containsServer(server.getAddress())``` because `master` group has not been added.
