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.
