Subject Re: Merge Namenode HA feature to 0.23
Date Fri, 09 Mar 2012 00:21:59 GMT

I applied the patch to branch-0.23. It compiles just fine. I built a
distribution tar, deployed it to a 4-node cluster, and ran some smoke tests
with HA enabled. All seemed good.

I also ran the following unit tests, which should exercise the relevant HA


Of these, they all passed except for TestOfflineEditsViewer and
TestPersistBlocks. These failed because the patch obviously doesn't include
changes to a few binary files which the tests rely on. Assuming that when
you merge to branch-0.23 you do an actual svn merge, and don't just apply
the patch, then these won't be a problem.
