    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Workaround
    • Affects Version/s: 2.9.1

      This issue affects only when IndexedFormat is used for log-aggregation by setting below properties:
      yarn.log-aggregation.file-formats=IndexedFormat
      yarn.log-aggregation.file-controller.IndexedFormat.class=org.apache.hadoop.yarn.logaggregation.filecontroller.ifile.LogAggregationIndexedFileController

      The fix is to set the below properties in yarn-site.xml and then restart Mapreduce HistoryServer and YARN services.
      yarn.log-aggregation.IndexedFormat.remote-app-log-dir-suffix and yarn.nodemanager.remote-app-log-dir-suffix to same value "logs-ifile" which serves AggregationLogDeletionService

      Description

      AggregationLogDeletionService does not honor yarn.log-aggregation.IndexedFormat.remote-app-log-dir-suffix. AggregationLogService writes the logs into /app-logs/<user-dir>/logs-ifile where as AggregationLogDeletion tries to delete from /app-logs/<user-dir>/logs.

      Workaround is to set yarn.log-aggregation.IndexedFormat.remote-app-log-dir-suffix and yarn.nodemanager.remote-app-log-dir-suffix to same value "logs-ifile" and Restart HistoryServer which serves AggregationLogDeletionService

      AggregationLogDeletionService has to check the format and based upon that choose the suffix. Currently it only checks the older suffix yarn.nodemanager.remote-app-log-dir-suffix.

      AggregatedLogDeletionService tries to delete older suffix directory.
