Subject [jira] [Commented] (HDFS-3095) Namenode format should not create the storage directory if it doesn't exist
Date Thu, 15 Mar 2012 04:19:55 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13229879#comment-13229879
] 

Todd Lipcon commented on HDFS-3095:
-----------------------------------

I kind of disagree. Mount points should not be in directories that are writable by the hdfs
user.... and making the user mkdir all of the storage dirs before running the NN format is
pretty unfriendly.
