Subject [jira] Updated: (MAPREDUCE-807) Stray user files in mapred.system.dir with permissions other than 777 can prevent the jobtracker from starting up.
Date Mon, 24 Aug 2009 12:03:59 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-807?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amar Kamat updated MAPREDUCE-807:
---------------------------------

    Release Note: The JobTracker tries to delete the mapred.system.dir when it is starting
up (with the job recovery disabled). The fix provided by this jira is that JobTracker will
fail (bail out) with AccessControlException if it fails to delete files/directories in mapred.system.dir
due to access control issues.

> With restart disabled, the jobtracker does a _rm -rf_ of the mapred.system.dir. If the
mapred.system.dir contains user files with permissions other than 777 then the jobtracker
gets stuck in a loop trying to delete the mapred.system.dir (and each time failing with AccessControlException).
