Aaron T. Myers updated HDFS-2941:
---------------------------------
Attachment: HDFS-2941.patch
Turns out some of the tests end up calling
TransferFsImage#downloadImageToStorage with localPaths set to null. The only
difference between this patch and the last is an extra null check in
TransferFsImage#downloadImageToStorage. This should address the test failures.
Unless there are further comments, I'm going to commit this pending Jenkins
based on Todd's earlier +1, since the difference between this patch and the
last is trivial.
