pre-created during startup (was: ZKFailoverController should implicitly ensure

> Key: HADOOP-10182
> URL: https://issues.apache.org/jira/browse/HADOOP-10182
> Project: Hadoop Common
> Issue Type: Bug
> Components: ha
> Affects Versions: 2.3.0
> Reporter: Ivan Mitic
> Assignee: Ivan Mitic
>
> Currently, a manual ZK format step is necessary before ZKFailoverController
> can join leader election. This generally adds overhead on what is needed to
> configure an HA cluster. My proposal is to always ensure that parent znodes
> exist during startup of the ZKFailoverController. If folks do not want to
> make this a default, we can put it under a config.
