> 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.
