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. jg
