      Description

      HA mode has two master, firstMaster and secondMaster; at the beginning, SecondMaster is active, firstMaster is standby.
      After secondMaster sends the openregion request to rs , the rs begins to launch regions, and the secondMaster just happened to be arbor; firstMaster becomes active and receives the zk message (node changed opend), but the region state in firstMaster memory is not opening, firstMaster sends the send closeRegion to rs, the region will never be on-line.
      Other versions should also exist the problem.
