Review request for Ambari, Dmytro Grinenko, Dmitro Lisnichenko, and Jonathan
Hurley.
Bugs: AMBARI-22240
https://issues.apache.org/jira/browse/AMBARI-22240
Repository: ambari
Description
-------
It looks like the consistent item here is that Kerberos is enabled, and that's
where this bug surfaces. It looks like when we switch the {{clusterconfig}}
entities to {{setSelected(true)}}, that those values are not being saved into
the database. When the transaction completes, they're all zero!:
{noformat}
ambari=# select config_id, type_name, stack_id, version, version_tag, selected,
unmapped from ambari.clusterconfig where type_name = 'cluster-env' order by
version_tag;
config_id | type_name | stack_id | version | version_tag | selected
| unmapped
-----------+-------------+----------+---------+----------------------+----------+----------
43 | cluster-env | 8 | 1 | version1 | 0
| 0
54 | cluster-env | 8 | 2 | version1507910265301 | 0

The fix I currently have in place forces the db to flush writes, and it appears
to be working. Not 100% sure why that's the case, and why only when enabling
Kerberos. Testing various RU/EU/PU scenarios to make sure nothing else is
broken.
