Date Wed, 20 May 2009 17:37:45 GMT

-------------------------------------------------------------

Updated to include older releases which also have shuffles and other related Map- and Reduce-specific
system information that are currently being logged to userlogs/attempt_###_r_###/syslog. If
the logging of this information could be moved out to the main TaskTracker log then this would
facilitate the information being picked up by Chukwa.

information consolidated in task tracker log or job history log file for down stream log collection
and analysis program (Chukwa) to pickup.
