Allen Wittenauer commented on HDFS-8241:
----------------------------------------
HDFS-5138 was such a total screw-up. I'm astounded as to how many people were
watching that JIRA and still thought it was OK to completely nuke operational
procedures out of the water in the non-HA case.
I've had discussions with [~sanjay.radia] to restore -finalize so that future
generations of branch-2 users aren't caught by surprise. At this point,
especially with branch-2 regularly tossing operations folks under the bus if it
is worth the effort. It might be easier to go ahead and remove the -finalize
option so that it's a fatal error rather than silently failing like it does
now. [~cwimmer], do you have any opinions on this?
