The error is propagated up as an HTTP 500 error: > {code:title=HTTP/500} > While building a service check command for YARN, there were no healthy eligible hosts: unhealthy[], maintenance[c6404.ambari.apache.org] > {code} > This message should be shown to the end user. Otherwise, nothing happens in the UI and there is no indication of an error. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
