Tsz Wo (Nicholas), SZE commented on HADOOP-6051:
------------------------------------------------

No one should use distcp to copy a single file anymore!  Just kidding ... we have to fix this.

> 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.
