How Do I Connect to Spark Shell from MRS?

Log in to the Master node in the cluster as user root.
Run the following command to configure environment variables:
source Client installation directory/bigdata_env
If Kerberos authentication is enabled for the cluster, authenticate the user. If Kerberos authentication is disabled, skip this step.
Command: kinit MRS cluster user

Example:
- If the user is a machine-machine user, run kinit -kt user.keytab sparkuser.
- If the user is a human-machine user, run kinit sparkuser.
Run the following command to connect to Spark shell:
spark-shell
