Subject [jira] [Commented] (HIVE-18785) Make JSON SerDe First-Class SerDe
Date Mon, 02 Jul 2018 14:53:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-18785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16530034#comment-16530034

BELUGA BEHR commented on HIVE-18785:
------------------------------------

[~aihuaxu] some documentation still needs to be updated:

 
{quote}
*JSON* 

ROW FORMAT SERDE 
'org.apache.hive.hcatalog.data.JsonSerDe' 
STORED AS TEXTFILE

 
Stored as plain text file in JSON format.

The JsonSerDe for JSON files is available in Hive 0.12 and later.


In some distributions, a reference to hive-hcatalog-core.jar is required.
{{ADD JAR /usr/lib/hive-hcatalog/lib/hive-hcatalog-core.jar;}}

> According to the [Hive SerDe Docs|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-RowFormats&SerDe],
there are some extra steps involved in getting the JSON SerDe to work:
> {quote}
> ROW FORMAT SERDE 
> 'org.apache.hive.hcatalog.data.JsonSerDe' 
> STORED AS TEXTFILE
> In some distributions, a reference to hive-hcatalog-core.jar is required.
> ADD JAR /usr/lib/hive-hcatalog/lib/hive-hcatalog-core.jar;
> {quote}
> I would like to propose that we move this SerDe into first-class status:
> {{STORED AS JSONFILE}}
> The user should have to perform no additional steps to use this SerDe.
