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

             Summary: Make RpcServer#processRequest logic more robust
                 Key: HBASE-16670
                 URL: https://issues.apache.org/jira/browse/HBASE-16670
             Project: HBase
          Issue Type: Bug
            Reporter: Yu Li
            Assignee: Yu Li
            Priority: Minor


Currently in {{RpcServer#processRequest}}, we will check whether the request header has parameters but missed handling the abnormal case, so if there's no param in the header, it will throw NPE like below:
