Subject [jira] [Commented] (HDFS-3094) add -force option to namenode -format command
Date Wed, 14 Mar 2012 21:04:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13229609#comment-13229609

Todd Lipcon commented on HDFS-3094:

Moved this to the HDFS project.

If you don't mind, please also add a "-nonInteractive" flag -- we have the hooks already in
trunk to implement it. The use case is that scripts may want to run non-interactively, where
pre-existence of the dirs is an error.

in the local file system.
> We should add a -force option which when present the user is not prompted.
