Jean-Daniel Cryans resolved KUDU-1934.
--------------------------------------
Resolution: Not A Problem
Assignee: Jean-Daniel Cryans
Fix Version/s: NA
Target Version/s: (was: 1.4.0)
Resolving as not a problem. This is a mix of the version mismatch which was
preventing the tservers to fully heartbeat and KUDU-1125 which made it so that
each heartbeat was then generating about 1860 writes per second on the master
over about 2 weeks.

> 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.
