>                 URL: https://issues.apache.org/jira/browse/HADOOP-2052
>             Project: Hadoop
>          Issue Type: Bug
>          Components: mapred

>             Fix For: 0.15.0
> When the mappers of distcp finish, the status page in the web gui reports the data copied.
> However, the reported number is far away from the real number, which is very misleading.
> For example, a particular mapper task_200710131713_0001_m_000000_0  reported: 
> Finished. Bytes copied: 4.3g
> However, it does not say which file.
> I thought it was for part-00000. But the file size of part-00000
> is about 9GB.
> It will be much clearer if the status report  say something like:
> Finished copy file-xxxx: 4.3g
> That way, I can easily check whether the size is correct.
