It's worth pointing out that starting the cluster took 4+ hours on 1000 nodes in 0.14 too. In other words, it was extremely expensive and a major cause of downtime. > Remove unused NameNode startup option -finalize > --- > > Key: HDFS-8241 > URL: https://issues.apache.org/jira/browse/HDFS-8241 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode >Affects Versions: 3.0.0 >Reporter: Brahma Reddy Battula >Assignee: Brahma Reddy Battula >Priority: Minor > Fix For: 3.0.0 > > Attachments: HDFS-8241-002.patch, HDFS-8241-003.patch, HDFS-8241.patch > > > Command : hdfs namenode -finalize > 15/04/24 22:26:23 INFO namenode.NameNode: createNameNode [-finalize] > *Use of the argument 'FINALIZE' is no longer supported.* To finalize an > upgrade, start the NN and then run `hdfs dfsadmin -finalizeUpgrade' -- This message was sent by Atlassian JIRA (v6.3.4#6332)

-
Thanks [~brahmareddy] for updating the patch. Minor nit:
{code:title=HDFSCommands.md}
Runs the namenode. More info about the upgrade, rollback and finalize is at
[Upgrade Rollback](./HdfsUserGuide.html#Upgrade_and_Rollback).
{code}
Would you remove finalize in the sentence?

Akira AJISAKA commented on HDFS-8241:
-
Hi [~brahmareddy], I have additional two comments.
# Would you remove the option from enum {{HdfsServerConstants.StartupOption}}?
# Would you remove the option from document entirely? We have deprecated the
option in the document of trunk and branch-2 by HDFS-8351, we can remove it in
trunk.
I'm +1 if these are addressed.

Konstantin Shvachko commented on HDFS-8241:
---
Historically, initial implementation of upgrade HADOOP-702 did not have the
finalize startup option, only the admin command. {{StartupOption.FINALIZE}} was
requested later HADOOP-1604 because people wanted to be able to start new
software even if they forgot to {{-finalizeUpgrade}} before shutting down the
cluster.

Q. do folks feel that a startup -finalize option to NN is a good interface in ADDITION to admin command to finalize? Clearly we needs the admin command to finalize since one does not want to restart the NN to finalize. > Remove unused Namenode startup option "FINALIZE" > - > > Key: HDFS-8241 > URL: https://issues.apache.org/jira/browse/HDFS-8241 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode >Affects Versions: 2.7.0 >Reporter: Brahma Reddy Battula >Assignee: Brahma Reddy Battula > Attachments: HDFS-8241.patch > > > Command : hdfs namenode -finalize > 15/04/24 22:26:23 INFO namenode.NameNode: createNameNode [-finalize] > *Use of the argument 'FINALIZE' is no longer supported.* To finalize an > upgrade, start the NN and then run `hdfs dfsadmin -finalizeUpgrade' -- This message was sent by Atlassian JIRA (v6.3.4#6332)

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.
