We installed HDP using root account successfully and the services came up after the install ok with no issues. But now, all services are down and we see the message "Connection failed: [Errno 111] Connection refused to sibi1b.gov.calgary.ab.ca:"
Not sure what is going on...Anyone had this issue and the resolution. Any help will be greatly appreciated.
Rebooting the server didn't help as well.

dont know what i did..but i tried restarting each service manually using command line and it started working. One wierd thing is that if i try to start all the services from the Ambari dashboard it does not work. But i try to start all the services from the hosts page which says "start all host components" it works. Also the zookeeper service keeps stopping all the time. otherthan that all the services are running fine. Any suggestions will be greatly appreciated.

Please check this stpes:-
1. Make sure hostname is right, iptables, selinux are stop
2. Check ps -aef for each process and kill it from cli [if you are able to see the process running]
3. Start the process from ambari.
let me know if it works.

One time I forgot this setting and I encountered the same problem.
The clocks of all the nodes in your cluster and the machine that runs the browser through which you access Ambari Web must be able to synchronize with each other.

I have same problem with Metrics Collector Process: Connection failed: [Errno 111] Connection refused to dnode01.cedar.cluster.ada:6188
NTP is enabled on all 16 nodes, but there is no positive affect
I'm not sure how the status of NTP on Browsing Host (which is not part of cluster) can affect the operation of cluster?
Can help with my case? Please let me know, if you need more details

You are responding to an old thread (July 2017) and I am pretty sure members are ignoring. It's advisable to open a new thread could you reformat your questions in a new thread.

I was just checking one of the issues you raised chandramouli muthukumaran Jun 14, 2016 at 03:24 PM. You received a couple of answers from me and Ashnee Sharma but unfortunately, you didn't accept either of the answers, this is unacceptable as HCC members go a long way to help whenever you open a thread and any solution provided if it resolved the issue should benefit other members who encounter the same issue.
Please ensure members who give solutions to your problems are rewarded this helps to keep member motivated to respond.
