Vinod K V reassigned MAPREDUCE-899: ----------------------------------- Assignee: Vinod K V > When using LinuxTaskController, localized files may become accessible to > unintended users if permissions are misconfigured. > --------------------------------------------------------------------------------------------------------------------------- > > Key: MAPREDUCE-899 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-899 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: tasktracker > Reporter: Vinod K V > Assignee: Vinod K V > > To enforce the accessibility of job files to only the job-owner and the > TaskTracker, as per MAPREDUCE-842, it is _trusted_ that the setuid/setgid > linux TaskController binary is group owned by a _special group_ to which only > TaskTracker belongs and not just any group to which TT belongs. If the trust > is broken, possibly due to misconfiguration by admins, the local files become > accessible to unintended users, yet giving false sense of security to the > admins. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
