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

             Summary: HistoryServerArchiveFetcher isn't compatible with old version
                 Key: FLINK-12184
                 URL: https://issues.apache.org/jira/browse/FLINK-12184
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.8.0, 1.7.2, 1.6.4
            Reporter: Yumeng Zhang


If we have old verison json files in history server, the HistoryServerArchiveFetcher can't convert legacy job overview. It will throw the NullPointerException when trying to convert legacy job overview because the tasks don't have the "pending" field.
