Subject [jira] Commented: (HADOOP-3090) dynamically add/subtract dfs.name.dir directories
Date Wed, 26 Mar 2008 17:29:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12582357#action_12582357

Sameer Paranjpye commented on HADOOP-3090:

It'd be better to introduce a 're-apply config' feature for the Namenode. Then we could add/remove
nodes and do other such things without bouncing the namenode.

>            Priority: Minor
> It would be very beneficial to be able to add and subtract dfs.name.dir entries on the
fly.  This would be used when one drive fails such that another location could be used to
keep image and edits redundancy.
