-----------------------------

             Summary: Clearing registeredStates map should be protected in SharedStateRegistry#clear
                 Key: FLINK-6651
                 URL: https://issues.apache.org/jira/browse/FLINK-6651
             Project: Flink
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


{code}
  public void clear() {
    registeredStates.clear();
  }
{code}
In other places of SharedStateRegistry, lock is taken on registeredStates before operation.
We should do the same for clear() method.
