> *STR:*
> 1) Deploy cluster with 3 nodes (Zookeeper server on every node)
> 2) Enable Resource manager HA mode
> 3) Remember value of 'yarn.resourcemanager.zk-address' property
> 4) Add fourth host to the cluster
> 5) Add Zookeeper server component to added host
> 6) Restart Zookeeper service
> *Expected results:*
> 1) Restart indicator should be present near YARN service
> 2) Value of 'yarn.resourcemanager.zk-address' property should be changed (should contains
internal name of previously added host)
> *Actual results:*
> 1) There are not restart indicators near YARN
> 2) Value of 'yarn.resourcemanager.zk-address' is the same as previously
> *(STR continue):*
> 7) Delete Zookeeper server component from host which was in cluster initially
> *Expected results:*
> 1) Restart indicator should be present near YARN service
> 2) Value of 'yarn.resourcemanager.zk-address' property should be changed accordingly
> *Actual results:*
> 1) There are not restart indicators near YARN
> 2) Value of 'yarn.resourcemanager.zk-address' is the same as previously
