Subject [jira] [Commented] (HDFS-8241) Remove unused Namenode startup option "FINALIZE"
Date Sat, 25 Apr 2015 14:22:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14512506#comment-14512506

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?
