In this lab which is the spark master and which are slaves. Can you please list out the names.
@Subrata_kumar The role of master in spark is Resourse Manager which allocates the resourses in standalone cluster and Worker nodes are the slave nodes.
To know the worker nodes in the cluster you can get information from resourse manager http://rm01.itversity.com:19288/cluster/nodes
You can watch the below video to understand different spark execution modes
