Robert Chansler updated HADOOP-3327:
------------------------------------
Release Note: (was: Reduces the waitiing time between map output fetch
re-tries during the end of the shuffle by aggressively notifying the JobTracker.
ReadTimeOuts during shuffle are treated differently: Reducer notifies the
JobTracker immediately for a readTimeout and backs off for more time.)
Editorial pass over all release notes prior to publication of 0.21. bug
> Shuffling fetchers waited too long between map output fetch re-tries
