Alexander Belyak commented on IGNITE-1075:
------------------------------------------
addData method calls many times and must be fast, what if I print warning when
DataStreamer creating?
> IgniteDataStreamer doesn't throw an exception if there are no data nodes

> If you call {{addData}} method, but there are no data nodes, you will never
> know about it. Looks like it is returned in a future, but it's
> counterintuitive to call it on each operation just to check for exception.
> Probably we should print out these errors in logs as well.
