-----------------------------------------
Attachment: h5188_20130915.patch
Thanks Junping for reviewing the patch.
h5188_20130915.patch:
- removes DatanodeInfo.EMPTY_ARRAY;
- always creates debugLoggingBuilder like before for supporting changing log
level at runtime.
For simple JIRAs, non-committer can review and +1 on patches. Although the
patch here is not small, I think this one is a simple JIRA since all changes
are straightforward. If you are uncomfortable, I could find someone the review
this.
