@miguno I test this on my cluster just now.
The topology is more simple "spout ----> bolt0 ---->bolt1", and each
component only have one executor;
I did't met the situation what you said, first I kill bolt1, and after 2
second bolt0 know bolt1 died and close the connection. And then after 31s,
bolt0 start connect to another worker that contain bolt1.
After bolt0 connect to new bolt1, new bolt1 receive immediately, I see this
through ui acked number;
1 First I kill bolt1 at 21:48:07;
2 bolt0 know bolt1 died at 21:48:08
