Hanifi Gunes commented on DRILL-1780:
-------------------------------------
Just seen your comment. Does not look similar. This is an implementation
problem as accessing a list should ideally follow a bound-check. Besides an
empty result set is not an error case. User needs to be notified accordingly.
DRILL-1373 seems like handling & showing execution failures. I will review this
patch.

> Web UI does not seem to recognize that the underlying result set is empty and
> blindly tries accessing items. This raises IndexOutOfBounds which portrays
> itself as an ugly HTTP 500.
