Move the cluster size slider left or right to change the number of nodes that will be available to the cluster.
Note:You cannot scale a cluster down to less than the original size of the cluster.
To change the period of inactivity that causes the cluster to terminate, click the checkbox Terminate after, then click the required inactivity period from the drop-down list.
Note:Scaling a cluster up will boost your compute power but will not increase cluster’s disk space.
