Raghu Angadi commented on HADOOP-5826:

I think it is better for someone with more familiarity with distcp to review.

My comments from a brief look at the patch :

- it might throw exception if used like 'distcp -basedir /a/b /a/b /dst'
- does simple 'distcp /dir0/dir1 /dst' create /dst/dir1 directory or move contents for dir1 into /dst? If it is former, then test case does not seem to test feature.
- The implementation changes the destination path but does not explicitly create the extra directories. Will it satisfy preserving the properties of those directories? (ie. '-basedir /a /a/b/c /dst' may not preserve properties for /dst/b and /dst/b/c).
distcp could have an option to preserve the full source path

Fix For: 0.21.0

It would be helpful to have an option that preserves the full source path when copying files from one location to another. This is specially important when archiving/moving files from one cluster to another one.
