-------------------------------------------
Summary: Regenerate keytab skips some keytabs on repaired host
Key: AMBARI-25173
URL: https://issues.apache.org/jira/browse/AMBARI-25173
Project: Ambari
Issue Type: Bug
Reporter: Dmitry Lysnichenko
Assignee: Dmitry Lysnichenko
*STR*
After repairing a failed master node (single, not HA). Ambari has external db.
Repair should also work if cluster is kerberized. Repair means following
procedure (some steps are skipped for clarity):
1. terminate failed node, start a new one
2. start ambari on new node
3. *regenerate all keytabs*
4. reinstall components
5. start / restart all components
Ambari has external db, containing the successful installation before repair.
*The problem*
When calling regenerate keytabs some do get created without any keys:
- smokeuser.headless.keytab
- spnego.service.keytab
Quick analysis revealed that in case of some of the keytabs ambari stores to db
a cache location on the hard drive. Since, however, that cache is note there on
the new instance and so ambari for some reason fails to regenerate those
specific keytabs.
*Version where this worked*
In ambari version 2.7.1.0 this has already worked.
We are currently using 2.7.100.0-266
I also tried 2.7.3.0 and the issue is present there as well.
