Subject [jira] Commented: (HDFS-966) NameNode recovers lease even in safemode
Date Wed, 14 Apr 2010 19:08:51 GMT

    [ https://issues.apache.org/jira/browse/HDFS-966?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12857029#action_12857029
] 

Konstantin Shvachko commented on HDFS-966:
------------------------------------------

This looks like a simple change, but could have serious consequences. Could you please elaborate
on the motivation, possible problems, +/-. 
One  question I see is what happens if lease recovery starts, when not all blocks have been
reported (during startup)?
