Brock Noland updated HIVE-5380:
-------------------------------
Release Note: Apache Hive recommends that custom ObjectInspectors created
for use with custom Serdes have a no-argument constructor in addition to their
normal constructors for serialization purposes. See HIVE-5380 for more details.
> Non-default OI constructors should be supported for backwards compatibility

> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.13.0
> Reporter: Brock Noland

> 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.
