-------------------------------------
Hi, [~navis], this jira is trying to support table level configurable encoding,
i take a look at HIVE-6329, do you mean you want to implement column level
configurable encoding? If yes, that should be a quite different implementation.
But that would be valuable as well, and i'm glad to see that.
> Hive multi serialization encoding support

> Key: HIVE-7142
> URL: https://issues.apache.org/jira/browse/HIVE-7142
> Project: Hive
> Issue Type: Improvement
> Components: Serializers/Deserializers
> Reporter: Chengxiang Li
> Assignee: Chengxiang Li

> 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.
