      Description

      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.
