Ravi Gummadi commented on MAPREDUCE-1657:
-----------------------------------------
In tasklog servlet, the problem is even when the task log files don't exist,
the first place an error is seen is authorization check.
Avoiding authorization check for viewing task logs if job-acls.xml file doesn't
exist would solve the problem.
> After task logs directory is deleted, tasklog servlet displays wrong error
> message about job ACLs
