shanyu zhao commented on HIVE-5405:
-----------------------------------

I understand that javaXML is not a preferred configuration choice. But since we are providing a configuration option instead of removing JavaXML support in HIVE-1511 we need to make sure they actually work.

> Prior to HIVE-1511, running hive join operation results in the following exception:
> java.lang.RuntimeException: Cannot serialize object

> sorImpl.java:43)
> 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.
