@Matthias Tewordt

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

reverse lookup fails with

** server can't find 23.251.117.40.in-addr.arpa.: NXDOMAIN

Regarding your question

Can you check your /etc/named.conf file disable by setting it to no

currently there is no /etc/named.conf file. I believe this is because I am using the Azure DNS service. Do you think I should install bind ?

I use both private and public IP addresses in /etc/hosts

eg

40.117.159.94 10.0.0.6 myhdf.eastus.cloudapp.azure.com myhdf

40.117.251.23 10.0.0.5 mtvm6.eastus.cloudapp.azure.com mtvm6

104.41.128.170 10.0.0.7 mtvm5.eastus.cloudapp.azure.com mtvm5

If you are using both Private and public I think the entry should look rather like this, more elegant !! Your earlier entry will not work as you have concatenated 2 IP's

40.117.159.94 10.0.0.6 myhdf.eastus.cloudapp.azure.com myhdf

####################### Private IP's #######################
40.117.159.94 myhdf.eastus.cloudapp.azure.com myhdf
40.117.251.23 mtvm6.eastus.cloudapp.azure.com mtvm6
104.41.128.170 mtvm5.eastus.cloudapp.azure.com mtvm5
#######################   Public IP's #######################
10.0.0.6 myhdf.eastus.cloudapp.azure.com myhdf
10.0.0.5 mtvm6.eastus.cloudapp.azure.com mtvm6
10.0.0.7 mtvm5.eastus.cloudapp.azure.com mtvm5

Replace that on all the servers and let me know

Geoffrey, really cool: the registration of the HDF cluster was now successful. The error was the missing reverse DNS on Azure. I have read the Azure article you suggested and implemented everything. Then it worked. You made my day thanks ! Now I will proceed with the HDF installation.

another question on this: where do you propose the databases in the HDF cluster ? Can I install them on one of the nodes, i.e. mtvm6, or better on the myhdf with ambari server or better elsewhere ?
