Lefty Leverenz commented on HIVE-7142:
--------------------------------------
This should be documented in wiki DDL sections "Row Format, Storage Format, and
SerDe" and "Add SerDe Properties" (although ideally the SerDe doc would have a
section with details about SERDEPROPERTIES):
* [DDL -- Row Format, Storage Format, and SerDe |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-RowFormat,StorageFormat,andSerDe]
* [DDL -- Add SerDe Properties |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-AddSerDeProperties]
* [SerDe | https://cwiki.apache.org/confluence/display/Hive/SerDe]
The jira's description could easily be turned into a release note.
> 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
> Labels: TODOC14
> Fix For: 0.14.0
>
> Attachments: HIVE-7142.1.patch.txt, HIVE-7142.2.patch,
> HIVE-7142.3.patch, HIVE-7142.4.patch
>
>
> 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.
