Imran Rashid commented on SPARK-6235:
-------------------------------------

[~sammysheep] are you discussing the use case for task results > 2G?  Or large 
records?  Or did you mean one of the parts that was supposed to be fixed in the 
plan above?

I don't deny there is _some_ use for large task result -- I just haven't heard 
much demand for it (in fact you're the first person I've heard from).  Given 
that, I don't expect to see it fixed immediately.  You could open another jira, 
though honestly for the moment I think it would be more of a place for folks to 
voice their interest.

(I'm pretty sure nothing has changed since 2.4.0 on what is fixed and what is 
not.)
