Veena Basavaraj commented on SQOOP-1795:
----------------------------------------
[~jarcec] The reason why having a wrapper class is one way to solve is to
exactly do the same thing, that is make sure we read and parse once,

> The situation of dealing with the post data is very tricky IMHO.
> 1. {{getRequest().getReader()}} must be called at the first place. As reading
> position cannot be reset, you might get unexpected result without notice.
> SQOOP-1784 is a case of the situation.
> 2. Sqoop client sends post data as a JSON object rather than query string
> format. Usually it'd suggest to wrap the JSON object as value, and key can be
> named as "jsonObject". The server will call
> {{ctx.getParameterValue("jsonObject")}} to get the value.
> I'd suggest to have a {{getRawPostData()}}, so that callers can put finger
> away from {{getReader()}}.
