Brock Noland commented on HIVE-1511:
------------------------------------
FWIW I altered this patch to use Kryo as opposed to the XML Encoder as part my
work on HIVE-5068. The test auto_join25.q gives me the error below:
{noformat}
com.esotericsoftware.kryo.KryoException: Class cannot be created (missing
no-arg constructor): org.antlr.runtime.CommonToken
{noformat}
which is a similar probably to what I am fighting with in HIVE-5068.
