---------------------------------

             Summary: Need to implement PersistenceDelegate for org.antlr.runtime.CommonToken
                 Key: HIVE-5405
                 URL: https://issues.apache.org/jira/browse/HIVE-5405
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.12.0
            Reporter: shanyu zhao
            Assignee: shanyu zhao


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
        at java.lang.Class.newInstance0(Class.java:357)
        at java.lang.Class.newInstance(Class.java:325)
        at sun.reflect.GeneratedMethodAccessor14.invoke(Unknown Source)
        at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAcces
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.
