> YARN has an implicit dependency on ZOOKEEPER.  It currently didn't declare an explicit
dependency because HDFS had one.
> Enabling the following settings in YARN requires ZOOKEEPER:
>   * yarn.resourcemanager.recovery.enabled 
>   * yarn.nodemanager.recovery.enabled
>   * yarn.resourcemanager.ha.enabled
>   * hadoop.registry.rm.enabled
> In addition, these properties are related to ZOOKEEPER and should be empty if ZOOKEEPER
is not installed:
>   * yarn.resourcemanager.zk-address 
>   * hadoop.registry.zk.quorum
