Brock Noland commented on HIVE-5405:
------------------------------------
Hey,
Sorry I wasn't clear, I am in favor of this patch ("I am +1 on the patch") and
feel we should have done this in HIVE-5263 ("RIght, in HIVE-5263 we didn't
perform this update so hive.plan.serialization.format=javaXML won't actually
work."), but I want to understand why you want to do this so I can understand
what scenarios javaXML is preferable.
Looking forward to your response.

> URL: https://issues.apache.org/jira/browse/HIVE-5405
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: shanyu zhao

> Attachments: HIVE-5405.patch

> Prior to HIVE-1511, running hive join operation results in the following
> exception:
> java.lang.RuntimeException: Cannot serialize object
> at
> org.apache.hadoop.hive.ql.exec.Utilities$1.exceptionThrown(Utilities.
> java:639)
> at java.beans.XMLEncoder.writeStatement(XMLEncoder.java:426)

> Caused by: java.lang.InstantiationException: org.antlr.runtime.CommonToken

> 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.
