Subject [jira] Commented: (HBASE-12) when hbase regionserver restarts, it says "impossible state for createLease()"
Date Thu, 07 Feb 2008 20:21:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12566776#action_12566776
] 

stack commented on HBASE-12:
----------------------------

Are regionservers bouncing Jean-Daniel?  That is, are they going down then coming back up
again soon after?  Check the logs under the regionservers themselves to see.  Enable DEBUG
too.  You'll get picture of whats going on (See FAQ for how).
