> distcp does not skip copying file if we are updating single file
> ----------------------------------------------------------------

> Key: MAPREDUCE-644
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-644
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: distcp
> Reporter: Ravi Gummadi
> Assignee: Ravi Gummadi
> Attachments: d_singlefile_update.patch
>
>
> distcp doesn't skip copying file when we do -update on single file if the
> destfile already exists.
> When we do
> hadoop distcp -update srcfilename destfilename
> it seems to be comparing checksums of srcfilename and
> destfilename/srcfilename and so skip is not done. It should compare checksums
> of srcfilename and destfilename.
