Initial job has not accepted any resources; check your cluster UI

15/09/19 10:28:44 WARN cluster.YarnScheduler: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources

This message in log means that Hadoop cluster does not have resources which are asked by Job.

I submitted Spark job on my test local cluster , and got this message.

Additional logs also show following ,

My cluster had only 3 GB RAM so Yarn cannot allocated what Spark was asking
