Subject [jira] [Commented] (HBASE-4268) Add utility to entirely clear out ZK
Date Thu, 19 Jan 2012 01:04:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13188859#comment-13188859

Karthik K commented on HBASE-4268:

I had put in ZOOKEEPER-729 sometime ago, for the exact reason in the past. 

With zk 3.4.2 , we can delete recursively as : 

./bin/zkCli.sh rmr /hbase 

>From the latest comment, seems like the command has been renamed in future releases though:

> In disaster scenarios, sometimes some cruft is left over in ZK, when it would be better
to do a truely clean startup. We should add a script which allows the admin to clear out ZK
while the cluster is down.
