Review request for hive.


Changes
-------

remove whitespaces.


Bugs: HIVE-7142
    https://issues.apache.org/jira/browse/HIVE-7142


Repository: hive-git


Description
-------

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:
CREATE TABLE person(id INT, name STRING, desc STRING)ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
WITH SERDEPROPERTIES("serialization.encoding"='GBK');
or
ALTER TABLE person SET SERDEPROPERTIES ('serialization.encoding'='GBK'); 
LIMITATIONS: Only LazySimpleSerDe support "serialization.encoding" property in this patch.
