> Key: AMBARI-25264
> URL: https://issues.apache.org/jira/browse/AMBARI-25264
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.6.2
> Reporter: Myroslav Papirkovskyi
> Assignee: Myroslav Papirkovskyi
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 2.6.2
>
>
> Now service checks are performed for any appropriate host during HOU. We
> should tune behaviour without API change to add some host selection
> restrictions.
> {code:java}
> [
> { "hosts": ["host1"], "service_checks": ["KAFKA", "ZOOKEEPER"] }
> ,
> { "hosts": ["host2"], "service_checks": ["ZOOKEEPER"] }
> ,
> { "hosts": ["host3", "host4"], "service_checks": ["CUSTOMSERVICE"] }
> ]
> {code}
> - Each service check will be performed for all hosts from hosts section.
> e.g. CUSTOMSERVICE check will be run on both host3 and host4
> - In case there is no service component on proposed host the upgrade request
> will be failed. This means that user should change upgrade plan and post it
> again.
