Subject [jira] [Commented] (HIVE-5405) Need to implement PersistenceDelegate for org.antlr.runtime.CommonToken
Date Tue, 01 Oct 2013 18:27:28 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13783195#comment-13783195
] 

Brock Noland commented on HIVE-5405:
------------------------------------

RIght, in HIVE-5263 we didn't perform this update so hive.plan.serialization.format=javaXML
won't actually work.  One more question, I am just curious as to why you are setting hive.plan.serialization.format
to javaXML? It's useful in our tests but in general it should be a unperformant configuration
choice.

> Prior to HIVE-1511, running hive join operation results in the following exception:

> HIVE-1511 introduced a new (and set to default) hive plan serialization format Kryo,
which fixed this problem by implementing the Kryo serializer for CommonToken. However, if
we set the following in configuration file:
> <property>
> <name>hive.plan.serialization.format</name>
> <value>javaXML</value>
> </property>
> We'll see the same failure as before. We need to implement a PersistenceDelegate for
the situation when "javaXML" is set to serialization format.
