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.
