------------------------------------
Summary: Job recovery may fail if staging directory has been
deleted
Key: MAPREDUCE-4850
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4850
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv1
Affects Versions: 1.1.1
Reporter: Tom White
Assignee: Tom White
The job staging directory is deleted in the job cleanup task, which happens
before the job-info file is deleted from the system directory (by the
JobInProgress garbageCollect() method). If the JT shuts down between these two
operations, then when the JT restarts and tries to recover the job, it fails
since the job.xml and splits are no longer available.
