Deleting a User

Updated at: Aug 17, 2021 GMT+08:00

The administrator can delete an MRS cluster user that is not required on MRS Manager. Deleting a user is allowed only in clusters with Kerberos authentication enabled or normal clusters with the EIP function enabled.

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

The operations described in this section apply only to clusters of versions earlier than MRS 3.x.

For clusters of MRS 3.x or later, see Deleting a User.


  1. Access MRS Manager. For details, see Accessing Manager.
  2. On MRS Manager, click System.
  3. In the Permission area, click Manage User.
