>            Reporter: Chesnay Schepler

>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 1.6.0
>
>
> As a prerequisite for a cleaner implementation of FLINK-9280 we should
>  * extend the RestClient to allow the upload of Files
>  * extend FileUploadHandler to accept mixed multi-part requests (json + files)
>  * generalize mechanism for accessing uploaded files in {{AbstractHandler}}
> Uploaded files can be forwarded to subsequent handlers as an attribute, similar to the
existing special case for the {{JarUploadHandler}}. The JSON body can be forwarded by replacing
the incoming http requests with a simple {{DefaultFullHttpRequest}}.
> Uploaded files will be retrievable through the {{HandlerRequest}}.
> I'm not certain if/how we can document that a handler accepts files.
