    [ https://issues.apache.org/jira/browse/HDFS-3094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13233160#comment-13233160

Arpit Gupta commented on HDFS-3094:

Thanks for the review Todd. I will make appropriate changes to the branch 1 and trunk.

bq. I don't follow the following comment:
+ //make sure the user did not sent force or noninteractive as the clusterid or an empty clusterid
Can you clarify it?

What i mean there is that if the user entered a wrong command where they did not specify a

./bin/hadoop namenode -format -clusterid -force

> add -nonInteractive and -force option to namenode -format command

> Currently the bin/hadoop namenode -format prompts the user for a Y/N to setup the directories
in the local file system.
> -force : namenode formats the directories without prompting
> -nonInterActive : namenode format will return with an exit code of 1 if the dir exists.
