Matei Zaharia updated MAPREDUCE-1258:
-------------------------------------

    Fix Version/s: 0.21.0

I've committed this to 0.21 as well, to let this logging feature continue to work as in 0.20.

> The MAPREDUCE-706 patch seems to have left an unfinished TODO in the Fair Scheduler -
namely, in the dump() function for periodically dumping scheduler state to the event log,
the part that dumps information about jobs is commented out. This makes the event log less
useful than it was before.
> It should be fairly easy to update this part to use the new scheduler data structures
(Schedulable etc) and print the data.
