[jira] [Created] (MAPREDUCE-6892) Issues with the count of
failed/killed tasks in the jhist file
Peter Bacsko created MAPREDUCE-6892:
---------------------------------------
Summary: Issues with the count of failed/killed tasks in the jhist file
Key: MAPREDUCE-6892
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6892
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: client, jobhistoryserver
Reporter: Peter Bacsko
Assignee: Peter Bacsko
Recently we encountered some issues with the value of failed tasks. After parsing the jhist file, {{JobInfo.getFailedMaps()}} returned 0, but actually there were failures.
Another minor thing is that you cannot get the number of killed tasks (although this can be calculated).
The root cause is that {{JobUnsuccessfulCompletionEvent}} contains only the successful map/reduce task counts. Number of failed (or killed) tasks are not stored.
