Devaraj Das commented on MAPREDUCE-1457:
----------------------------------------
Some comments:
In the trunk patch and in the Y20 patch, the call to task.taskCleanup in
Child.java should be within a privileged block.
In the Y20 patch, the calls to JobHistory.initDone() and JobHistory.init()
should be within privileged blocks, and use the JobTracker's ugi. Within
JobHistory.logSubmitted, there is a call to set up the writer for userLogFile.
That should be within a privileged block and use the user's ugi.
> For secure job execution, couple of more UserGroupInformation.doAs needs to
> be added
