> See HBASE-19530. When regions are created initial state should be CLOSED. Bug was discovered while debugging
flaky test TestSplitTableRegionProcedure#testRollbackAndDoubleExecution with numOfSteps set
to 4. After updating daughter regions in meta when master is restarted, startup sequence of
master assigns all OFFLINE regions. As daughter regions are stored with OFFLINE state, daughter
regions are assigned. This is followed by re-assignment of daughter regions from resumed SplitTableRegionProcedure.
