To use Spark on an existing Hadoop Cluster, do we need to install Spark on all nodes of Hadoop?

Question Posted / Nikhil Verma

Answer Posted / Nikhil Verma

No, you don't have to install Spark on all nodes. You can run Spark applications using the YARN resource manager, which is part of Hadoop. However, you need to ensure that all the necessary dependencies are available and properly configured.
