Boris Shkolnik commented on HADOOP-4045:
----------------------------------------
Manual testing done:
1. Mount two directories (one for Edits and Image, one for Edits only).
2. create some files
3. unmount one of them and wait for checkpoint (or create a file) , verify that
failed dir is removed
4. unmount another one (optional) - more verifications
5. mount one back - (checkpoint or new files), verify that checkpointtime is
updated and files have the same size and MD5
6. mount the other one (optional) - more verifications
7. repeat 3 and 5
8. check WebUI all the time.
> Increment checkpoint if we see failures in rollEdits
