Subject [jira] [Commented] (HBASE-6858) Fix the incorrect BADVERSION checking in the recoverable zookeeper
Date Fri, 12 Oct 2012 23:59:03 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6858?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13475448#comment-13475448
] 

Gregory Chanan commented on HBASE-6858:
---------------------------------------

Another potentially silly question...

We are trying to prevent all these cases where a client is writing the same data.  There are
a couple of variables here:
- Same vs different client
- Same vs different time

Do either of these matter?  Why do we care if we try to do the same write?

> Thanks for Stack and Kaka's reporting that there is a bug in the recoverable zookeeper
when handling BADVERSION exception for setData(). It shall compare the ID payload of the data
in zk with its own identifier.
