Should I install spark on all nodes of yarn cluster?

Question Posted / saumay mishra


Should I install spark on all nodes of yarn cluster?..

Answer / Shailly

When running Apache Spark on a Hadoop YARN cluster, you only need to install the Spark daemons (namenode, resourcemanager, nodemanager, and historyserver) on the master node. The worker nodes (node managers) do not require Spark installation, as they run the user-submitted tasks.
