Vinod K V updated MAPREDUCE-842: -------------------------------- Release Note: Modified TaskTracker and related classes so that per-job local data on the TaskTracker node has right access-control. Important changes: - All files/directories of the job on the TaskTracker are now user-owned by the job-owner and group-owner by a special TaskTracker's group. - The permissions of the file/directories are set to the most restrictive permissions possible. - Files/dirs shareable by all tasks of the job on this TT are set proper access control as soon as possible, i.e immediately after job-localization and those that are private to a single task are set access control after the corresponding task's localization. - A new configuration entry hadoop.log.dir corresponding to the hadoop.log.dir in TT's configuration is now needed in task-controller.cfg > Per-job local data on the TaskTracker node should have right access-control > --------------------------------------------------------------------------- > > Key: MAPREDUCE-842 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-842 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Components: tasktracker > Reporter: Arun C Murthy > Assignee: Vinod K V > Fix For: 0.21.0 > > Attachments: HADOOP-4491-20090623-common.1.txt, > HADOOP-4491-20090623-mapred.1.txt, HADOOP-4491-20090703-common.1.txt, > HADOOP-4491-20090703-common.txt, HADOOP-4491-20090703.1.txt, > HADOOP-4491-20090703.txt, HADOOP-4491-20090707-common.txt, > HADOOP-4491-20090707.txt, HADOOP-4491-20090716-mapred.txt, > HADOOP-4491-20090803.1.txt, HADOOP-4491-20090803.txt, > HADOOP-4491-20090806.txt, HADOOP-4491-20090807.2.txt, > HADOOP-4491-20090810.1.txt, HADOOP-4491-20090810.3.txt, > HADOOP-4491-20090811.txt, HADOOP-4491-20090812.txt > > -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
