Sorry, I don't have circles working on this jira currently. It's on my TODO list. I will work
on it soon. Thank you!

>                 URL:
>             Project: Hive
>          Issue Type: New Feature
>          Components: Serializers/Deserializers
>            Reporter: Niels Basjes
>            Assignee: Ferdinand Xu
>         Attachments: HIVE-9252.1.patch
> In HIVE-6047 the option was created that a jar file can be hooked to the definition of
a function. (See: [Language Manual DDL: Permanent Functions|]
> I propose to add something similar that can be used when defining an external table that
relies on a custom Serde (I expect to usually only have the Deserializer).
> Something like this:
> {code}
>     ...
>     [USING JAR|FILE|ARCHIVE 'file_uri' [, JAR|FILE|ARCHIVE 'file_uri'] ];
> {code}
> Using this you can define (and share !!!) a Hive table on top of a custom fileformat
without the need to let the IT operations people deploy a custom SerDe jar file on all nodes.
