[jira] Created: (MAPREDUCE-1595) LinuxTaskController is too strict
on the initial ownership of files/dir.
LinuxTaskController is too strict on the initial ownership of files/dir.
------------------------------------------------------------------------
Key: MAPREDUCE-1595
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1595
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: security, task-controller
Reporter: Vinod K V
Linux task controller is too strict now w.r.t the initial ownership of the files/dir that it tries to make as secure as possible. Currently, it expects, for e.g, the mapred-local/tasktracker/user-dir to be both user-owned and group-owned by TT. This leads to unrecoverable failures in some corner cases.
It can instead allow the files/dirs to be owned either by TT *or* by the jobOwner.
