@ed day Please check link:- https://issues.apache.org/jira/browse/AMBARI-8513 this was the bug i ambari 1.7.0. The usual work flow when ambari-server is creating the agents is as follow: Ambari-server host provisions by ssh all ambari-agents Every ambari-agent needs to callback to https://ambari.test.com:8440 and register itself in the server. All agents are registered and now you can install "stuff" in them through ambari. If you configuring multinode cluster then the problem was the agents in different nodes couldn't execute the callback cause they couldn't reach ambari-server url in that port. Maybe this isssue is related to ports 8440 and 8441 in the ambari-server host. Please open this port and try once again or use ambari version 2.0.0 or later. Hope it helps! ... View more
