      Description

      https://github.com/apache/hbase/blob/eca904e0fb438461a8da3f37cea3eaf496988be9/hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java#L3624

      if rs has invalid znode, and restart master, ui will throw NPE.
      i encountered this problem during the upgrade.

      workaround: restart HBase.
