Rich Haase commented on HADOOP-1540:
------------------------------------
Found a bug in the patch. The CopyCommitter doesn't know about exclusions so
it will throw an exception when it tries to preserve permissions on a Path that
was excluded. Need to refactor the change to separate exclusion logic into a
class that is usable by the CopyMapper and CopyCommiter. Since the code has to
be refactored to work correctly it makes sense to define an interface for
exclusions.
> distcp should support an exclude list

> been copied over under the current srcPath).
