> Key: AMBARI-19293
> URL: https://issues.apache.org/jira/browse/AMBARI-19293
> Project: Ambari
> Issue Type: Bug
> Components: ambari-agent, ambari-server
> Affects Versions: 2.5.0
> Reporter: Doroszlai, Attila
> Assignee: Doroszlai, Attila
> Priority: Critical
> Fix For: 3.0.0

>
> If Ambari executes component installation in parallel, execution of
> {{link_configs}} in the after-install hook for one component may interfere
> with the {{configure}} step of another component's installation. This may
> cause loss of configuration files.
> What's more, {{configure}} from different components may also interfere with
> each other.
