Overview

Scenario

Websites of different components are created and hosted on the Master or Core nodes in the MRS cluster by default. You can view information about the components on these websites. The websites can be accessed only through the network of the cluster and are not released on the Internet for security reasons. Common users can access the websites by creating an ECS with a graphical user interface (GUI) in the network.

If you do not want to create an extra ECS, you can turn to technical experts or development engineers. They can use the dynamic port forwarding function of the SSH channel to allow you to access the websites.

The Loader page is a graphical data migration management tool based on the open source Sqoop WebUI and is hosted on the Hue WebUI.

NOTE:

Remotely log in to the Master2 node and run the ifconfig command. In the command output, eth0:FI_HUE refers to the floating IP address of Hue. Record the actual value of inet. If you cannot query the floating IP address of Hue on the Master2 node, switch to the Master1 node to query the floating IP address and then record it. If there is only one Master node, log in to this Master node to query the floating IP address and then record it.
