Hi, [~jingzhao]
I changed {{getNameNodeProxy}} to {{getRollEditsTask}} in branch-2. Could you
take a look? Thanks.

Lei (Eddy) Xu updated HDFS-4176:
Attachment: HDFS-4176-branch-2.0.patch
Hi, [~jingzhao]
I made a patch for {{branch-2}}. The conflicts between trunk and branch-2 are
due to {{MultipleNameNodeProxy}} not exist on branch-2. So I put
{{getActiveNodeProxy.rollEditLog()}} to a simple {{Callable#call()}}.
Would you mind to take another look? Thanks
