> *Steps*
> # Deploy HDP-2.3.6 cluster with Ambari 2.2.2.0 (AMS is configured in
> distributed mode)
> # Upgrade Ambari to 2.4.0.0 and let it complete
> # Open Ambari web UI and hit "Restart all required" under Actions menu
> *Result*
> The operation fails while trying to restart Metrics Collector as it tried to
> make a WebHDFS call while HDFS was not started:
> {code}
> Traceback (most recent call last):
