Aaron T. Myers updated HDFS-2100:
---------------------------------
Attachment: hdfs-2100.0.patch
Patch which adds a new test method to cover this case.
This patch also cleans up {{TestStorageRestore}} generally by making it not
extend {{TestCase}}, getting rid of a few compiler warnings, and fixing a typo.

> Though running multiple 2NNs isn't supported, accidentally doing so should
> not result in HDFS metadata corruptions. We should add a test case to
> exercise this possibility when name.dir.storage.restore is enabled, which is
> a particularly delicate code path.
