Subject [jira] Commented: (HBASE-3502) Can't open region because can't open .regioninfo because AlreadyBeingCreatedException
Date Fri, 04 Feb 2011 21:57:30 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12990763#comment-12990763

Todd Lipcon commented on HBASE-3502:

Why just WARN and not throw an exception if it can't rename? Other than that looks good.

> This tries to create the .regioninfo file.  Seems like that was started over at the NN
but then the RS died shortly afterward.  Its stopping the Region opening.  I suppose I could
try and open it for append to shut it then reopen?
