> In HIVE-5263 we started serializing OI's when cloning the plan. This was a great boost
in speed for many queries. In the future we'd like to stop copying the OI's, perhaps in HIVE-4396.
> Until then Custom Serdes will not work on trunk. This is a fix to allow custom serdes
such as the Hive JSon Serde work until we address the fact we don't want to have to copy the
OI's. Since this is modifying the byte code, we should recommend that the no-arg constructor
be added.
