Ravi Gummadi updated MAPREDUCE-1657:
------------------------------------
Attachment: MR1657.20S.1.patch
Attaching patch for earlier version of hadoop. Not for commit here.
Patch makes tasklog servlet to do authorization check only if job-acls.xml file
exists. Also added a proper error message for the case of accessing task logs
from tasklog servlet when the whole task log directory is not existing for a
task. Added 2 testcases to TestWebUIAuthorization for (a) allowing all users to
view task logs when job-acls.xml file not existing and (b) getting proper error
code when the whole task log directory not existing.
> After task logs directory is deleted, tasklog servlet displays wrong error
> message about job ACLs
