cluster installation - can't proceed during master selection

Hey there,

I'm trying to install a new Hadoop cluster with Ambari 2.7. During the master selection of the services I get following error in the web interface:

0 status code received on POST method for API: /api/v1/stacks/HDP/versions/3.0/recommendations

After that the next button grays out and I can't continue. I tried looking in the ambari-server log, but there gets nothing logged during this error.

I would appreciate any help.

Best regards,

Markus

Were you able to resolve this? Or find out what the root cause was?

The issue is because there is an error in network communication. Best way to solve it is to run the ambari wizard in a machine on the same subnet as ambari.
