Hemanth Yamijala updated MAPREDUCE-1435: ---------------------------------------- Resolution: Fixed Hadoop Flags: [Reviewed] Status: Resolved (was: Patch Available) I committed this patch to trunk. Thanks, Ravi ! > symlinks in cwd of the task are not handled properly after MAPREDUCE-896 > ------------------------------------------------------------------------ > > Key: MAPREDUCE-1435 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1435 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: tasktracker > Affects Versions: 0.22.0 > Reporter: Amareshwari Sriramadasu > Assignee: Ravi Gummadi > Fix For: 0.22.0 > > Attachments: 1435.patch, 1435.v1.patch, 1435.v2.patch, 1435.v3.patch, > 1435.v4.patch, MR-1435-y20s.patch > > > With JVM reuse, TaskRunner.setupWorkDir() lists the contents of workDir and > does a fs.delete on each path listed. If the listed file is a symlink to > directory, it will delete the contents of those linked directories. This > would delete files from distributed cache and jars directory,if > mapred.create.symlink is true. > Changing ownership/permissions of symlinks through ENABLE_TASK_FOR_CLEANUP > would change ownership/permissions of underlying files. > This is observed by Karam while running streaming jobs with DistributedCache > and jvm reuse. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
