Bikas Saha commented on HDFS-2863:
----------------------------------
1.Will do
2.I added the TestFSNamesystem to be a class for adding future unit tests for
the same source class. The test is not really HA specific since the dups can
occur in the edits.dirs config itself right?
3.The unit test tests what the function does. So IMO it makes sense the way its
written currently. The fact that we currently support a single shared edits dir
is not related to the test and should be ideally covered in a functional sanity
test for the HA config feature right?
Will update the patch shortly.
> Failures observed if dfs.edits.dir and shared.edits.dir have same directories.
