    Description

      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.
