> URL: https://issues.apache.org/jira/browse/AMBARI-13967
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.0
> Environment: HDP 2.2
> Reporter: Hari Sekhon
> Priority: Critical
>
> One of my clusters has Ranger service installed (but not yet configured)
> which causes Ambari to be unable to manage it's services.
> Doing Actions -> "Start All" from Dashboard doesn't absolutely nothing (no
> pop-up appears, no outputs or errors) and doing Hosts -> Actions -> All Hosts
> -> Stop All Components fails with the following exception:
> {code}2015-11-19 09:59:59,893 - Execution of 'mysql -u root
> --password=<password> -h <fqdn> -s -e "select version();"' returned 1. ERROR
> 2003 (HY000): Can't connect to MySQL server on '<fqdn>' (111)

> This is a bug when Ambari is in a state where it's unable to control it's
> services. I worked around it for now by removing the Ranger service via the
> API until I have time to come back and properly redeploy it later.
> Technically I can understand something failing the underlying database check
> for a single service, but I've noticed that Ambari has a lot of fringe
> conditions around state and having an installed but unconfigured service
> breaks it.
> Also there should never be a scenario where Start All does absolutely nothing
> and doesn't feed back to the user in any way.
