Do you need to install spark on all nodes of yarn cluster?

Question Posted / Desh Deepak

Answer Posted / Desh Deepak

When running a Spark application on a YARN cluster, it is not necessary to install Spark on all nodes. Instead, only the resource manager and worker nodes with required resources (memory and CPU) should have Spark installed. The rest of the worker nodes can continue to run other YARN applications.
