Subject [jira] [Created] (MAPREDUCE-2406) Failed validate copy in distcp
Date Mon, 28 Mar 2011 20:45:05 GMT
Failed validate copy in distcp
------------------------------

                 Key: MAPREDUCE-2406
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2406
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.21.0
            Reporter: Rosie Li
            Priority: Minor


Each time the distcp is done, {{validateCopy(srcstat, absdst)}} will be called. 
When doing distcp, if the -pb(preserve block size) is not set, the dst will use the default
block size. However, if the src file use block size other than the default block size, and
-pb is not set, after copying, the src and dst will have different block size. It will not
pass the validateCopy check in this case.
