Hi, Sorry for late response, held up in other work and will start the tutorial again later. However, "Please let us know if you are trying to start ambari server with Non-Root user account?" - No, I am using root to start and also to check the status. The error mentioned above is on issue of status or start command. [root@sandbox-hdf ~]# ambari-server status In fact I am unable to find the directory "/var/run/ambari-server". I am using the port mentioned while I start the VM. I believe the start up page is displayed correctly so no issue there. But I will try to check further later. Thanks.

I am following the tutorial: https://hortonworks.com/tutorial/realtime-event-processing-in-hadoop-with-nifi-kafka-and-storm/section/2/ Based on initial requirements, I have download the sandbox: HDF_3.0.2.0_vmware_28_11_2017.ova When I started the VM, I got the host and IP for Welcome screen and SSH terminal (Untitled.png). I registered the host in my windows hosts file. I am able to open the SSH terminal (on Gitbash and chrome both) and change the root password successfully. I am also able to go to the Welcome screen. When I click on Dashboard, it opens 2 tabs. 1 tab is for tutorial which is working fine. Another tab is for Ambari dashboard, which cannot be opened. It is giving me "refuse to connect" error. When I go to SSH terminal and try to check status or start ambari service I receive following error. [root@sandbox-hdf ~]# ambari-server status
