> Currently Hive only support serialize data into UTF-8 charset bytes or 
> deserialize from UTF-8 bytes, real world users may want to load different 
> kinds of encoded data into hive directly. This jira is dedicated to support 
> serialize/deserialize all kinds of encoded data in SerDe layer. 
> For user, only need to configure serialization encoding on table level by set 
> serialization encoding through serde parameter, for example:
> {code:sql}
> CREATE TABLE person(id INT, name STRING, desc STRING)ROW FORMAT SERDE 
> 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe' WITH 
> SERDEPROPERTIES("serialization.encoding"='GBK');
> {code}
> or
> {code:sql}
> ALTER TABLE person SET SERDEPROPERTIES ('serialization.encoding'='GBK'); 
> {code}
> LIMITATIONS: Only LazySimpleSerDe support "serialization.encoding" property 
> in this patch.
