Todd Lipcon commented on KUDU-1934:
-----------------------------------
Yea, I don't think once-a-second retries are that bad. Sure it's silly to do
for two weeks, but on the other hand, if a server is having issues for two
weeks, you'd probably notice it for other reasons, right?
I suppose we could have it shut down after inability to connect for some number
of hours, but seems kind of arbitrary.

> Related to KUDU-1933, I had mismatched 1.3 snapshots between the master and
> the tservers which caused them to try to reconnect to the master infinitely.
> Since they do it as fast as they can, the logs were quickly full of:

> Sounds like we should do backoff retries.
