If the component has an open source web UI, you can access it by clicking the web UI link in the component's basic information area.

NOTE:

For clusters with Kerberos authentication enabled, user admin does not have the management permission on each component. To access the web UI of each component, create a user who has the management permission on the corresponding component by referring to Creating an MRS Cluster User.
