Dmitry Buzolin commented on SPARK-18085:
----------------------------------------
I don't think you read my response with enough attention (I said REST API call
as well as UI).
The REST API returns JSON, isn't it? This JSON before it is delivered to the
clinet making a REST call is kept in where? Not in the thin air, in the memory
of SHS. I have nothing to add at this point, but I feel discouraged to continue
discussion with you.
Thanks,
Dmitry.
