Subject [jira] Commented: (HIVE-1411) DataNucleus throws NucleusException if core-3.1.1 JAR appears more than once on CLASSPATH
Date Thu, 22 Jul 2010 23:29:50 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12891392#action_12891392
] 

Paul Yang commented on HIVE-1411:
---------------------------------

About #4, I was able to reproduce the exception and verify the fix by creating a copy of the
datanucleus core jar in hive's lib directory.

Makes sense to me. Now that you mention it, I think I ran into a similar problem while using
the 'hadoop jar' command. It would unpack the jar, but include both the jar and the unpacked
classes in the classpath. If the jar contained datanucleus stuff, this would throw an exception.

Anyway, the fix looks good. +1
