[Timer-0:WARN] Logging$class: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources

Hi,

I am trying to connect to a new cluster I just set up.

And I get...
[Timer-0:WARN] Logging$class: Initial job has not accepted any resources; check 
your cluster UI to ensure that workers are registered and have sufficient 
resources

I must have forgotten something really super obvious.

My connection code is:
                SparkSession spark = SparkSession.builder()
                                .appName("JavaSparkPi")
                                .master("spark://10.0.100.81:7077")
                                .config("spark.executor.memory", "4g")
                                .config("spark.executor.cores", "2")
                                .getOrCreate();

My master is on 10.0.100.81, start with a simple start-master.sh. I have 2 
nodes, which i run with ./sbin/start-slave.sh spark://un.oplo.io:7077 
<spark://un.oplo.io:7077>.

I use Spark's own resource scheduler.
