RSA Product/Service Type: Security Analytics Warehouse
RSA Version/Condition: 10.4.x / 10.5.x
Platform: CentOS
Platform (Other): MapR
O/S Version: EL6
IssueAn administrator is unable to log into the MapR UI to manage Warehouse nodes.  
While the web server appears to be working as expected on the RSA Warehouse node, login attempts fail.
CauseThis issue can occur when the administrative account does not have the proper permissions to log into the MapR GUI.
ResolutionTo resolve the issue, follow the steps below.
  1. Confirm that the web server service is running on one of the Warehouse nodes.  
  2. SSH to each of the nodes in the cluster, and execute the command below to determine which node the MapR web server service is running on (as shown in the example below).                               
    # /opt/mapr/adminuiapp/webserver status


    This should display:
      User-added image
     

  3. If the service is not running, start it with the command below.

    # /opt/mapr/adminuiapp/webserver start


    This should yield results similar to the following:
    User-added image
  4. Open a browser, then navigate to the MapR UI, using the IP where the service is started + port 8443:
    https://<node_internal_ip_address>:8443

    Note that initial HTTPS connections have not passed a certificate to the browser yet, and a warning that the connection is not trusted typically appears. This message may be safely ignored.
  5. Now attempt login again with the desired account.
    1. If this login fails and the username/password combination is known good, issue the below command to assign proper permissions to the user. (being root in this example)
       
      # opt/mapr/bin/maprcli acl edit -type cluster -user root:fc

       
  6. Now login and the account should be able to successfully authenticate to the MapR UI.
If you are unsure of any of the steps above or experience any issues, contact RSA Support and quote this article number for further assistance.
