Deleting a User

The administrator can delete an MRS cluster user that is not required on MRS Manager.

If you want to create a new user with the same name as user A after deleting user A who has submitted a job on the client or MRS console, you need to delete user A's residual folders when deleting user A. Otherwise, the newly created user A may fail to submit a job.

To delete residual folders, log in to each Core node in the MRS cluster and run the following commands. In the following commands, $user indicates the folder named after the username.

cd /srv/BigData/hadoop/data1/nm/localdir/usercache/

rm -rf $user

Procedure

On MRS Manager, click System.
In the Permission area, click Manage User.
