Kai Sasaki commented on HDFS-7302:
----------------------------------
[~szetszwo] I understand the background of this ticket, so I'd like to confirm
what I should do here.
1. Remove "-rollingUpgrade downgrade" option from namenode startup
2. Update documentations about this option.
Is this right?
> namenode -rollingUpgrade downgrade may finalize a rolling upgrade
