TaskTracker.lcoalizeJob should not set permissions on job log directory
recursively
-----------------------------------------------------------------------------------
Key: MAPREDUCE-1609
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1609
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: tasktracker
Affects Versions: 0.22.0
Reporter: Amareshwari Sriramadasu
Assignee: Amareshwari Sriramadasu
Fix For: 0.22.0
Currently TaskTracker.lcoalizeJob sets permissions (570 with
LinuxTaskController) on job log directory recursively. When the tracker
restarts/reinits, if there are new tasks for the job, localizeJob would find
attempt log directories for the earlier tasks. If the job has many tasks, it
would spend significant time in chmod'ing.
Also, if a cleanup attempt is launched after the restart/reinit, we would hit
MAPREDUCE-1607.
