> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Reporter: Dmitry Lysnichenko
> Assignee: Dmitry Lysnichenko
> Priority: Blocker
> Fix For: 2.7.4

>
> *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.
