["Jeff Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-80?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12933378#action_12933378 ] 

Jeff Zhang commented on HIVE-80:
--------------------------------

Does anyone know whether Driver is thread-safe ? If so, each query can been executed by one Driver.
And I notice that in HWI for each session there is one Driver, it seems Driver should be thread-safe, just want to ensure about it.
