Subject [jira] [Commented] (HIVE-1511) Hive plan serialization is slow
Date Wed, 14 Aug 2013 22:19:48 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13740289#comment-13740289
] 

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.
