Alexander Belyak commented on IGNITE-1075:
------------------------------------------

addData method calls many times and must be fast, what if I print warning when DataStreamer creating?

> 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.
