Vinod Kumar Vavilapalli updated HADOOP-2165:
--------------------------------------------

    Attachment: patch_userlog_1.4.3.txt

Attaching a patch.

This adds hyperlinks to taskdetailshistory jsp page (links to stderr/stdout/syslog via tasklog servlet). For doing this, it adds a "INFO_URL" key-val pair to jobhistory's MapAttempt and ReduceAttempt start event log statements. Added a hyperlink to host and cleaned up error field so that it looks better.

> 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.
