I am happy you have succeeded. Next time you can now help someone with the setup of HDF in Azure 🙂
Yes, the database could be set on any node but as you have already Postgres installed for Ambari it's easier to have the other databases on the same host for easier management.

CAUTION:

When in production think of setting database replication in the future.

Once you have finished the setup If you found this answer addressed your question, please take a moment to log in and click the "Accept" link on the answer.

Keep me posted

/etc/hosts looks alright on all nodes

host -v -t A mtvm6.eastus.cloudapp.azure.com yields mtvm6.eastus.cloudapp.azure.com. 10 IN A 40.117.251.23 etc.

so to me this looks ok ...

Back to the basics, did you validate the below points?

And check the DNS resolution, The manual registration was successful on the Ambari host but failed on the 2 other nodes because it just can't locate them.

Can you upload the ambari-server.log ?

Geoffey, all done. How can I best upload the amber-server.log from the Azure service ? It is a huge file

@Matthias Tewordt

Can you get it to your local machine and maybe trim the last 200 or so lines or use an external website and provide the link to download because in here the format are restricted and the sizes too

Hi Geoffrey, thanks so much. Can you please share your email address? So I will share the link to Google Drive with Ambari log files. Thanks, Matthias

Geoffey, the Ambari Server is attached. Can you open it ?

ambariserverlog.zip

@Matthias Tewordt

That's quite bizarre in the logs you attached I see that Ambari is trying to load 2 different repos see below can you explain why?

Centos6

Could not load version definition for HDP-2.6 identified by http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.6.4.0/HDP-2.6.4.0-91.xml. null 

Centos7

Could not load version definition for HDP-2.6 identified by http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.6.5.0/HDP-2.6.5.0-292.xml. null

Check the current repos, you should see ambari,hdp and hdp-utils repos

$ ll /etc/yum.repos.d/

Validate the contents and share their contents

  • cat /etc/yum.repos.d/HDP.repo
  • cat /etc/yum.repos.d/ambari.repo
  • cat /etc/yum.repos.d/HDP-UTILS.repo

Check the OS version in my case its a Centos6 so you can grab the correct repo

cat /etc/redhat-release 
CentOS release 6.9 (Final)

Delete the HDP and HDP-Utils repos in /etc/yum.repos.d

rm -rf  HDP*

Clean the repos

# yum clean all

Validate, you shouldn't see HDP and HDP-Utils except for ambari.repo and some Centos stuff

# yum repolist 

For Ambari version 2.5 and above see the choice(attached ambari-hdp-matrix.jpg)

Download the correct HDP repos

See OS version above in my case Centos 6, the hdp in HDP 2.6 delivers both HDP and HDP-Utils

$ wget -nv http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.6.4.0/hdp.repo -O /tmp/hdp.repo

GPL repo

$ wget -nv http://public-repo-1.hortonworks.com/HDP-GPL/centos6/2.x/updates/2.6.4.0/hdp.gpl.repo -O /tmp/hdp.gpl.repo

After the above revalidate, you should be able to see new HDP*/ repos

# yum repolist

Now restart the cluster deployment

Geoffrey, I am running Red Hat RHEL 7. So don't you think I should opt for the CentOS 7 repos ?

@Matthias Tewordt

Yes definitely that's why I wanted you to match my output to your OS version!

The was also this error what is your processor?

"cannot resolve OS centos7-ppc to the supported ones: suse12,suse11,redhat7,debian7,redhat6,ubuntu14,ubuntu12. Family: null"

Please revert

here is a list of the files in yum.repos.d. Why remove all HDP repos ?? I suggest to eliminate the 2 public-repo-1... repos and leave the hdp.repo (see RHEL7 content below).

-rw-r--r--. 1 root root 306 May 31 2017 ambari.repo

-rw-r--r--. 1 root root 574 Jan 8 06:49 hdp.repo

-rw-r--r--. 1 root root 296 May 17 06:36 public-repo-1.hortonworks.com_HDP_centos7_2.x_updates_2.6.4.0_HDP-2.6.4.0-91.xml.repo

-rw-r--r--. 1 root root 242 May 17 06:09 public-repo-1.hortonworks.com_HDP-UTILS-1.1.0.22_repos_centos7.repo

-rw-r--r--. 1 root root 358 Jan 5 00:08 redhat.repo

-rw-r--r--. 1 root root 13955 Dec 3 2016 rh-cloud.repo

Here is the content of the hdp.repo : it looks alright to me ?
