I'm using linux fedora 23. First, there is no prompt "You can access SSH by $ ssh root@127.0.0.1 -p 2222" on startup screen. Second, when I try to connect from my terminal to started HDP 2.4 sandbox via ssh I got the error: $ ssh root@127.0.0.1 -p 2222 ssh: connect to host 127.0.0.1 port 2222: Connection refused ...

Hi, I recently set up Hadoop cluster with 4 nodes on single machine using vagrant and ambari, all within virtualbox residing on single physical machine. Now, I decided to modify the topology: remove 2 data nodes from the former machine and add 2 data nodes on another physical machine running its own virtualbox. I installed two hosts on second machine under virtualbox with vagrant. On the 'Add Host Wizard', Confirm Hosts step I fail with the error: "Host checks were skipped on 1 hosts that failed to register." Looking at the ambari-server log at /var/log/ambari-server/ambari-server.log I found the following log error: INFO:root:BootStrapping hosts ['c7003.ambari.apache.org'] using /usr/lib/python2.6/site-packages/ambari_server cluster primary OS: redhat7 with user 'vagrant' sshKey File /var/run/ambari-server/bootstrap/6/sshKey password File null using tmp dir /var/run/ambari-server/bootstrap/6 ambari: c7001.ambari.apache.org; server_port: 8080; ambari version: 2.2.2.0; user_run_as: root INFO:root:Executing parallel bootstrap ERROR:root:ERROR: Bootstrap of host c7003.ambari.apache.org fails because previous action finished with non-zero exit code (1) ERROR MESSAGE: Connection to c7003.ambari.apache.org closed. which hints that ambari-server is trying to start up c7003 node on its local virtualbox (although it is already running on the different machine). The communication between two machine is SSH passwordless and I checked it is working in both directions. Does amabari support the cluster that is distributed accross multiple machines?
