Oleksandr Alesinskyy created MAPREDUCE-4945:
-----------------------------------------------
Summary: FileOutputCommitter.abortTask should check a result of
outputFileSystem.delete(workPath, true);
Key: MAPREDUCE-4945
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4945
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: tasktracker
Affects Versions: 0.21.0, 0.20.205.0
Reporter: Oleksandr Alesinskyy
MAPREDUCE-1409 partially fixes a problem with an retained output of aborted
tasks - unfortunately, the fix is incomplete, there are cases when a
{{delete()}} method does neither deletes a file nor throws an exception, but
merely returns {{false}}. That means that its return value shall be checked
and if it is {{false}} and a file still exists an exception should be thrown.
