Hi @Shelton , here are further details: - I'm using CentOS7 virtual machine - I installed Hadoop 2.6 on it as per url: https://www.vultr.com/docs/how-to-install-hadoop-in-stand-alone-mode-on-centos-7 (this is same steps as official Hadoop installation doc) - Then I proceeded to install Ambari as per url guide: https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.6.2 - After Ambari server and Ambari agent are downloaded, I did an ambari-server setup. - Logged in to ambari on localhost:8080 and proceeded with "install cluster wizard". - Wherein it asks for hostname I entered localhost.localdomain (checked in hostname -f and in /etc also this is correct). - Selected option to manually setup host and not use SSH password. Clicked on Next and this is where it gives above error and fails to register host. Hope this info helps, please let me know if else needed. I have tried official Hadoop and Ambari installation guide several times but no help. Infact last time with same steps i was able to go to review page in cluster installation, but this time its failing earlier to that only. Thanks in advance.

Hi, I'm trying to install Ambari 2.6 on CentOS7 x64. I have HDP 2.6 already installed. These versions are compatible to each other per Horton Support Matrix.
When trying to create a cluster through wizard, the host registration is failing, below is the log error and I've also tried all common troubleshooting I could find online
= stop, reset, start server
= change hostname
= disable firewall
= change python code (https://community.cloudera.com/t5/Support-Questions/Ambari-server-host-register-failed/td-p/233413)
None of it seems to help. Looking forward to any help.
