Subject [jira] [Commented] (HIVE-9289) TODO : Store user name in session [Spark Branch]
Date Wed, 07 Jan 2015 19:47:35 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14268105#comment-14268105
] 

Xuefu Zhang commented on HIVE-9289:
-----------------------------------

Maybe I don't fully understand the code, but it seems a little concerning that session is
reused purely based on user name. Hive supports multiple sessions for the same user, and we
don't want such session is reused.

I also have a feeling that we don't have any session reuse (though we have code here and there
for that). If that's the case, we'd rather just get rid of the code.

[~chengxiang li], could you comment on this?
