Subject [jira] [Commented] (YARN-1222) Make improvements in ZKRMStateStore for fencing
Date Thu, 17 Oct 2013 00:48:42 GMT

    [ https://issues.apache.org/jira/browse/YARN-1222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13797483#comment-13797483

Vinod Kumar Vavilapalli commented on YARN-1222:
-----------------------------------------------

I meant blocking w.r.t the implementation and the patch conflicts more than the approach.
If we are changing the node structure on ZK via YARN-1307, this patch will be affected, no?

> Using multi-operations for every ZK interaction. 
> In every operation, automatically creating/deleting a lock znode that is the child of
the root znode. This is to achieve fencing by modifying the create/delete permissions on the
root znode.
