'Does Spark Application Master always run in the master node of EMR cluster or not
I have a EMR cluster (1 master node 1 core node) and I submitted my spark-application deploy mode is cluster mode.
From the documentation, I know the driver runs inside Spark Application Master given this deploy mode, but which node (master or core) will be selected by Yarn to run Spark Application Master?
Is it always master node?
Thanks.
