-------------------------------------
Summary: Task attempts that fail from the ASSIGNED state can
disappear
Key: MAPREDUCE-5982
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5982
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mr-am
Affects Versions: 2.2.1, 0.23.10
Reporter: Jason Lowe
If a task attempt fails in the ASSIGNED state, e.g.: container launch fails,
then it can disappear from the job history. The task overview page will show
subsequent attempts but the attempt in question is simply missing. For example
attempt ID 1 appears but the attempt ID 0 is missing. Similarly in the job
overview page the task attempt doesn't appear in any of the
failed/killed/succeeded counts or pages. It's as if the task attempt never
existed, but the AM logs show otherwise.
