> Based on the fix in HADOOP-8315, it's possible to deploy a secured HA cluster
> with SASL support for connection with Zookeeper. However it requires extra
> configuration for JAAS to initialize the Zookeeper client because the client
> will do another login in it even when ZKFC service actually has already
> passed the Kerberos login during its starting.
