Installing a Client on a Node Outside the Cluster

Prepare a Linux ECS outside the cluster. For details about the requirements, see Installing a Client on a Node Outside a Cluster.
Install the client to a directory, for example, /opt/client, on the node outside the cluster by referring to Installing a Client on a Node Outside a Cluster.
Check whether Kerberos authentication is enabled for the cluster.
- If yes, go to 4.
- If no, go to Installing Python 3.
Log in to FusionInsight Manager by referring to Accessing FusionInsight Manager (MRS 3.x or Later).
Create a user, for example, mrs-test. Set User Group to hadoop, Primary Group to hadoop, and Role to Manager_operator.
Log in to the client node as user root and run the following commands to configure environment variables for security authentication:
source /opt/client/bigdata_env

kinit mrs-test

Change the password upon the first authentication.
