Subject Re: issue about namenode format command
Date Wed, 23 Oct 2013 14:54:44 GMT
Looks like the doc's on apache are missing this info.

Format in Hadoop 2 supports the following options

-format [-clusterid cid ] [-force] [-nonInteractive]

-nonInteractive will not prompt but will fail if the name dir exists.

-force will not prompt and will delete the contents of the name dir.
