    Description

      In the implementation of MRClientProtocol, many methods can throw NullPointerExceptions. Instead of NullPointerExceptions, better to throw IOException with proper message.

      In the HistoryClientService class and MRClientService class has #verifyAndGetJob() method that return job object as null.

      getTaskReport(GetTaskReportRequest request) throws IOException;
      getTaskAttemptReport(GetTaskAttemptReportRequest request) throws IOException;
      getCounters(GetCountersRequest request) throws IOException;
      getTaskAttemptCompletionEvents(GetTaskAttemptCompletionEventsRequest request) throws IOException;
      getTaskReports(GetTaskReportsRequest request) throws IOException;
      getDiagnostics(GetDiagnosticsRequest request) throws IOException;
