Ravi Gummadi commented on MAPREDUCE-896: ---------------------------------------- unit tests passed on my local machine for this Y! 20 patch. > Users can set non-writable permissions on temporary files for TT and can > abuse disk usage. > ------------------------------------------------------------------------------------------ > > Key: MAPREDUCE-896 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-896 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: tasktracker > Affects Versions: 0.21.0 > Reporter: Vinod K V > Assignee: Ravi Gummadi > Fix For: 0.21.0 > > Attachments: MR-896.patch, MR-896.v1.patch, MR-896.v2.patch, > y896.v1.patch, y896.v2.1.fix.patch, y896.v2.1.fix.v1.patch, > y896.v2.1.fix.v2.patch, y896.v2.1.patch, y896.v2.patch > > > As of now, irrespective of the TaskController in use, TT itself does a full > delete on local files created by itself or job tasks. This step, depending > upon TT's umask and the permissions set by files by the user, for e.g in > job-work/task-work or child.tmp directories, may or may not go through > successful completion fully. Thus is left an opportunity for abusing disk > space usage either accidentally or intentionally by TT/users. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
