I am setting up an ambari cluster with 3 virtualbox VMs running Ubuntu 16.04LTS.
I followed this hortonworks tutorial.
However when I am going to create a cluster using Ambari Cluster Install Wizard I get the below error during the step 3 - "Confirm Hosts".
26 Jun 2017 16:41:11,553 WARN [Thread-34] BSRunner:292 - Bootstrap process timed out. It will be destroyed.

Bootstrap process timed out. It was destroyed.
I have read number of posts saying that this is related to not enabling Password-less SSH to the hosts. But I can ssh to the hosts without password from the server.
I am running ambari as non-root user with root privileges.
This post helped me.
I modified the users in host machines so that they can execute sudo commands without password using visudo command.
Please post if you have any alternative answers.
