> Currently, migration works but there's still a couple of rough edges:
> - HBASE-8045 finished the .META. migration but didn't remove ROOT, so it's
> still on the filesystem.
> - Data in ZK needs to be removed manually. Either we fix up the data in ZK
> or we delete it ourselves.
> - TestMetaMigrationRemovingHTD has a testMetaUpdatedFlagInROOT method, but
> ROOT is gone now.
> Elliott was also mentioning that we could have "hbase migrate" do the HFileV1
> checks, clear ZK, remove ROOT, etc.
