             Summary: Potential null object deference in AssignmentManager#handleRegion()
                 Key: HBASE-10182
                 URL: https://issues.apache.org/jira/browse/HBASE-10182
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu


Here is the related code, starting line 921:
{code}
          if (regionState == null
              || !regionState.isPendingOpenOrOpeningOnServer(sn)) {
            LOG.warn("Received OPENED for " + prettyPrintedRegionName
              + " from " + sn + " but the region isn't PENDING_OPEN/OPENING here: "
              + regionStates.getRegionState(encodedName));

            // Close it without updating the internal region states,
            // so as not to create double assignments in unlucky scenarios
            // mentioned in OpenRegionHandler#process
            unassign(regionState.getRegion(), null, -1, null, false, sn);
{code}
If regionState is null, we should not dereference it.
