Subject [jira] Updated: (HADOOP-4491) Per-job local data on the TaskTracker node should have right access-control
Date Mon, 10 Aug 2009 07:04:14 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4491?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod K V updated HADOOP-4491:
------------------------------

    Attachment: HADOOP-4491-20090810.1.txt

Attaching patch including most of the above comments.

bq. hadoop.log.dir in task-controller.cfg is not needed?
hadoop.log.dir is still needed to set permissions on userlogs/attempt-id directories to be
writable by the user's tasks and readable by TT for serving via web UI.
bq. One more point which I discussed with Vinod. The changes in common are at this point just
a simple convenience wrapper API around the java.io.File APIs for setting permissions. I propose
we move this into the mapred patch itself and open a JIRA to discuss the changes to common
more carefully.
Moved these changes into TaskTracker.PermissionsHandler. In future (via MAPREDUCE-759),  this
along with most of the remaining localization related code should be refactored into a separate
class.
