Subject [jira] Commented: (HIVE-1350) hive.query.id is not unique
Date Tue, 18 May 2010 22:54:54 GMT

    [ 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:


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