> 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.
