Subject [jira] [Commented] (HIVE-3913) Possible deadlock in ZK lock manager
Date Tue, 22 Jan 2013 18:16:13 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13559830#comment-13559830

Mikhail Bautin commented on HIVE-3913:
--------------------------------------

[~ashutoshc]: thanks for pointing this out. I took a look at HIVE-3537, and I think this is
a much simpler fix for a situation that I observed when the client attempts to acquire a lock,
but the ZK connection is closed for some reason and no reconnection is attempted.
