> When creating an upgrade, an HTTP error returned (such as a 500 error) is
> never propagated up to the end user.
> STR:
> - Setup a 4-host cluster with ZK, Yarn, HDFS
> - Install clients only on the 4th host
> - Place the 4th host into maintenance mode
> - Start an upgrade
> The server will correctly throw an exception since service checks cannot be
> scheduled since 4th host in maintenance mode is excluded. 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.
