Andrii Tkach created AMBARI-16643:
-------------------------------------
Summary: Ambari allows installing a component on more than one
host even with cardinality as 0-1
Key: AMBARI-16643
URL: https://issues.apache.org/jira/browse/AMBARI-16643
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.2.0
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Priority: Critical
Fix For: 2.4.0
ACTIVITY_ANALYZER is configured to have cardinality of 0-1, however from hosts
page I would add service to two hosts.
User should have been prevented from adding additional more than once instance
of this slave as it violates the cardinality constraint.
