> 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.
