Logging In to the CDLService Web UI

Scenario

After CDL is installed in an MRS cluster, you can manage data connections and visualized jobs using the CDL web UI.

This section describes how to access the CDL web UI in an MRS cluster.

CDL cannot fetch tables whose names contain the dollar sign ($) characters.

Prerequisites

• The CDL component has been installed in an MRS cluster and is running properly.
• A user with CDL management operation permissions has been created by referring to Creating a CDL User for the cluster with Kerberos authentication enabled.

Procedure

1. Log in to FusionInsight Manager as a user with CDL management operation permissions or as user admin (for clusters with Kerberos authentication disabled), and choose Cluster > Services > CDL.
2. Click the hyperlink next to CDLService UI to access the CDLService web UI.

   You can perform the following operations on the CDL web UI:

   • Driver Management: You can upload, view, and delete a driver file corresponding to the connected database.
   • Link Management: You can create, view, edit, and delete a data connection.
   • Job Management: You can create, view, start, pause, restore, stop, restart, delete, or edit a job.
   • ENV Management: You can create, view, edit, and delete Hudi environment variables.
