Subject [jira] Updated: (HADOOP-3327) Shuffling fetchers waited too long between map output fetch re-tries
Date Fri, 09 Oct 2009 04:19:31 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3327?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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
