Subject [jira] [Commented] (HBASE-8131) Create table handler needs to handle failure cases.
Date Sun, 17 Mar 2013 17:39:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8131?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13604681#comment-13604681

ramkrishna.s.vasudevan commented on HBASE-8131:
-----------------------------------------------

Need to check one more scenario where on master restart what happens to the zk lock.  From
the code i think it is an ephemeral node so that the znode should expire on master's expiry.
Will check that too just incase.

> In CreateTable Handler there are number of failure cases.  
> IOExceptions are common while creation of regioninfos, htableDescriptors etc.
> After this exception if i try to recreate the table using admin, we need to remove the
acquired table lock and also clear the ZKTable in memory cache so that the operation can be
retried.
