> YARN-4243 introduced the logic that lets retry establishing the connection when initializing
the {{ActiveStandbyElector}} adding the parameter {{failFast}}.
> {{ZKFailoverController#initZK}} should use this constructor with {{failFast}} set to
false, to let the ZFKC wait longer for the Zookeeper server be in a ready state when first
initializing it.
