Subject [jira] [Commented] (HIVE-14227) Investigate invalid SessionHandle and invalid OperationHandle
Date Mon, 25 Jul 2016 21:58:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15392731#comment-15392731
] 

Vaibhav Gumashta commented on HIVE-14227:
-----------------------------------------

[~aihuaxu] I think what [~szehon] is referring to here is that to implement session level
failover, it will help if we don't close the session on the server, when the client tcp socket
that opened the session gets closed.
