| N/A | BUG-86606 | After upgrading a cluster from Ambari 2.4.2 and HDP 2.5.2, Zeppelin
proxy user settings are not configured in
core-site.xml. | Manually configure hadoop.proxyuser.zeppelin.hosts and
hadoop.proxyuser.zeppelin.groups in
core-site.xml. |
| N/A | BUG-82900 | If hosts are in maintenance mode during the Enable Kerberos wizard, the kerberos client is not installed, and keytabs and principals are not created for these hosts. | For those hosts that were in maintenance mode while Kerberos was being enabled, the kerberos client needs to be installed. This is possible using the REST API, or using the Ambari Web UI by going to the affected host and choosing to Install clients. This will install the Kerberos client and allow you to successfully generate keytabs. To generate keytabs go to Admin > Kerberos > Regenerate Keytabs and choose the Only regenerate keytabs for missing hosts and components option. |
