[jira] Commented: (HIVE-1350) hive.query.id is not unique

["John Sichi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-1350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12868884#action_12868884 ] 

John Sichi commented on HIVE-1350:
----------------------------------

Random with no args is seeded by current time in millis, so when run from two different JVM's there's still a tiny chance that we can end up with the same query ID.  If we want to avoid that, we can use UUID instead:

http://java.sun.com/j2se/1.5.0/docs/api/java/util/UUID.html

But if we only care about uniqueness within the same JVM, then +1.
