@Ramon Wartala Sometimes such issue happens when you do not configure proper FQDN for the hosts so the principals are not correctly generated. Can you please confirm if you have the correct FQDN configured for all the hosts including this Zookeeper node? # Following command should show the FQDN configured hostname -f . If the FQDN is not correctly set earlier then you should try setting the FQDN correctly and then regenerate the keytabs again. ... View more

@Rajesh Reddy While loading ambari UI ambari APIs also tries to read the whole cluster information's which also includes Alerts definition, That actually makes many DB calls. Looks like your VM has some resource issues which is causing ambari to be very slow. (Thats why Ambari API calls are showing "ambari_server_performance" alert saying "Host resource exaustion") https://github.com/apache/ambari/blob/release-2.5.0/ambari-server/src/main/resources/alerts.json#L43-L45 Can you try killing some of the processes manually like Oozie and Zeppelin and then restart ambari server to see if it loads fine. . ...

@Rajesh Reddy We will need to see the Java Script call that is getting stuck. We can do so by using the "Developer Tools". For example open URL in Google Chrome and then click on the "Google Chrome Menu" --> "More Tools" --> Debugger Tools Can you please share the output of the Debugger tools Specially from the "Network" tab which tells the call that is keep trying to get the response. . Also try running the following Curl Command : # curl -u admin:admin -i -H 'X-Requested-By: ambari' -X POST -d '{"wizard-data":"{\"userName\":\"admin\",\"controllerName\":\"\"}"}'http://ambari.example.com:8080/api/v1/persist . You will need to replace the credentials and the ambari server hostname in the above command. ... View more

@Paul Bere Ambari uses It's own custom Form Authentication. But your screen shows a Browser (Basic Auth Window). Also the XDB (Which i guess oracle tomcat instance uses) suggests that you might be running Oracle On your Local machine ... it also uses port 8080. The password prompt is coming from there. Please stop any oracle instance on your local machine and then try accessing ambari again. ... View more

@Manoj Dixit I edited my above command .... as by mistake i mentioned Master Node instead of Ambari Node. Only Ambari Node is enough to be able to do passwordless ssh to all the cluster nodes. So you need to run the above mentioned commands only from Ambari Server Node. ... View more

@Manoj Dixit Yes, On the "Ambari Server" node you can run the following command to create the SSH keys: # ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): (I kept it EMPTY) Enter same passphrase again: (I kept it EMPTY) Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: ........ . Then you can run the following command to pass the authorization key entry to the cluster nodes. # ssh-copy-id -i ~/.ssh/id_rsa.pub localhost # ssh-copy-id -i ~/.ssh/id_rsa.pub node1.exmaple.com # ssh-copy-id -i ~/.ssh/id_rsa.pub node2.exmaple.com # ssh-copy-id -i ~/.ssh/id_rsa.pub node2.exmaple.com # ssh-copy-id -i ~/.ssh/id_rsa.pub node3.exmaple.com # ssh-copy-id -i ~/.ssh/id_rsa.pub node4.exmaple.com . This thing you need to do only from "Ambari Server" node ... View more
