[jira] [Updated] (AMBARI-17760) Ambari should perform service check
only healthy hosts
[ https://issues.apache.org/jira/browse/AMBARI-17760?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dmytro Grinenko updated AMBARI-17760:
-------------------------------------
Description:
We blindly pick first component in a row, if no preferred client components found
As solution, we should check for healthy candidate, and check the case - that first selected component could be not installed at all(i.e. not installed on any host). This could be happened if first picked up component is a slave with cardinality 0+
