Subject [jira] Commented: (HIVE-80) Allow Hive Server to run multiple queries simulteneously
Date Tue, 05 May 2009 23:36:30 GMT

    [ https://issues.apache.org/jira/browse/HIVE-80?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12706248#action_12706248
] 

Neil Conway commented on HIVE-80:
---------------------------------

BTW, one issue we've run into when running multiple queries by using multiple Drivers in a
client program is that HiveInputFormat seems to be dependent on a static "JobConf" variable,
so there's a race condition when running multiple queries concurrently.
