Accessing Web Pages of Open Source Components Managed in MRS Clusters

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.

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.

Accessing the Web UI of an Open Source Component

  1. Log in to MRS Manager.

    For details, see Accessing MRS Manager.

  2. Table 1 displays the steps to locate the entry for each component.
