Hostname of the first master node. The value is either [CLUSTER_NAME]-m in a standard or single node cluster, or [CLUSTER_NAME]-m-0 in a high-availability cluster, where [CLUSTER_NAME] is the name of your cluster.
dataproc-master-additional
Comma-separated list of hostnames for the additional master nodes in a high-availability cluster, for example, [CLUSTER_NAME]-m-1,[CLUSTER_NAME]-m-2 in a cluster that has 3 master nodes.
