Subject [jira] Created: (HADOOP-3350) distcp should permit users to limit the number of maps
Date Tue, 06 May 2008 02:57:55 GMT
distcp should permit users to limit the number of maps
------------------------------------------------------

                 Key: HADOOP-3350
                 URL: https://issues.apache.org/jira/browse/HADOOP-3350
             Project: Hadoop Core
          Issue Type: Improvement
            Reporter: Chris Douglas
             Fix For: 0.18.0


distcp provides no user-configurable setting to affect the number of maps run during a copy.
For large clusters, the current calculation- min(#bytes / 256MB, #nodes * 20)- can be overly
aggressive.
