Connection failed: [Errno 111] Connection refused to

Contributor

Hi,

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.

Thanks

Chandra

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.

3. Start the process from ambari.

One time I forgot this setting and I encountered the same problem.

Enable NTP on the Cluster and on the Browser Host

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.

Hello,

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
