Subject [jira] Commented: (HDFS-1073) Simpler model for Namenode's fs Image and edit Logs
Date Thu, 04 Nov 2010 17:47:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1073?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12928283#action_12928283
] 

Sanjay Radia commented on HDFS-1073:
------------------------------------

> 4) No more edits, but a new BN starts up, and thus asks for another roll. 
A backup NN should not ask for a roll. The primary should roll when it feels it is necessary.
