_temporary directories could be left in output directory sometimes
------------------------------------------------------------------
Key: MAPREDUCE-1272
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1272
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: task
Affects Versions: 0.20.1
Reporter: Amareshwari Sriramadasu
Priority: Critical
After a job-cleanup task cleans up _temporary directory, there are chances that
a speculative attempt could create it again since create file api creates all
parent directories.
