Veena Basavaraj commented on SQOOP-1795:
----------------------------------------
The answer is simple, you cannot predict everywhere in the code on the order in
which these methods will be called in future. Not sure what is not coming
across here:)

> 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()}}.
