["Ashutosh Chauhan (JIRA)" <ji...@apache.org>]

Ashutosh Chauhan updated HIVE-5411:
-----------------------------------

    Attachment: HIVE-5411.patch

This patch is bigger than I initially though because serializeExpression accepted ExprNodeFuncDesc as an argument, but it should really only accept ExprNodeGenericFuncDesc. Doing that resulted in quite a bit of refactoring in various classes. Additionally, this patch also includes:
* Since serialized expression is stored in job conf, serialized version needs to be xml-safe, so we Base64 encode it.
* Timestamp serialization of Kryo is buggy(in the same way Date serializer is), patch includes custom Serializer for it.
* It incorporates HIVE-5377
