-------------------------------------
Summary: Regenerating keytabs on re-imaged hosts results in error
during 'Creating Principals'
Key: AMBARI-16009
URL: https://issues.apache.org/jira/browse/AMBARI-16009
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.2.2
Reporter: Robert Levas
Assignee: Robert Levas
Priority: Blocker
Fix For: 2.2.2
We had a 1600 unsecured cluster initially, from which 700 nodes were destroyed.
Though Ambari-server knew of 1600 hosts, only 900 were heartbeating. At this
point we secured the cluster and everything was good. Then we brought back the
700 hosts, which started heartbeating with ambari-server.
At this point we did 'Regenerate Keytabs' which failed at the 'Create
Principals' step (image attached), as it was trying to re-create principal
which is already existing with kadmin, and with ambari-server.
