stack updated HBASE-8348:
-------------------------
Attachment: 8348v5.txt
Here are some mods to the last version of the patch making usage better reflect
the mutual exclusivity, moving upgrade up from package to commands, made usage
consistent so has '-' everywhere instead of '--' and then '-' sometimes in the
help, removed alternative version so commands -- alternatives too long.
> Polish the migration to 0.96

> 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.
