Subject [jira] Created: (ABDERA-33) Heavy map tasks should be scheduled first
Date Sat, 27 Jan 2007 19:24:49 GMT
Heavy map tasks should be scheduled first
-----------------------------------------

                 Key: ABDERA-33
                 URL: https://issues.apache.org/jira/browse/ABDERA-33
             Project: Abdera
          Issue Type: Improvement
            Reporter: Runping Qi



In many cases I noticed that a few  heavy map tasks finished really late since they were started
late too. When the jobtracker chooses map tasks for task trackers, it should takes the input
data size of the tasks into account, and try to assign the ones with large input first.
