Vinod K V updated HADOOP-2165:
------------------------------

    Attachment: HADOOP-2165-20080919.3.txt

Attaching patch fixing a possible NPE.

Ran "ant test-patch" which returned the following (*sigh* I should have done this with the
last patch itself.)

     [exec] -1 overall.
     [exec]     +1 @author.  The patch does not contain any @author tags.
     [exec]     -1 tests included.  The patch doesn't appear to include any new or modified
tests.
     [exec]                         Please justify why no tests are needed for this patch.
     [exec]     +1 javadoc.  The javadoc tool did not generate any warning messages.
     [exec]     +1 javac.  The applied patch does not increase the total number of javac compiler
warnings.
     [exec]     +1 findbugs.  The patch does not introduce any new Findbugs warnings.

No test-cases for this. Mostly jsp related changes.

Arun, can you please look at and commit this? Thanks.

> It will be very useful to be able to see the job's userlogs (the stdout/stderr/syslog
of the tasks) from the JobHistory page. It will greatly aid in debugging etc.
> At the very minimum we should have links from the JobHistory to the logs on the TT.
