How Do I Disable CAS Authentication for the Impalad Role in an MRS Cluster?

Question

How do I disable CAS authentication to call Impalad's queries API on a node outside the cluster to obtain metrics?

Answer

Log in to FusionInsight Manager, choose Cluster > Services > Impala, and click Configurations and then All Configurations. In the tab, choose Impalad(Role) > Customization. Add the parameter --webserver_cas_enable to impalad.customized.configs and set it to false. Save the configuration and restart the instance whose configuration expired. The system automatically disables CAS authentication.
