my sandbox is centos7 and the node is centos6, hopefully that doesnt make a difference. I followed this link https://community.hortonworks.com/storage/attachments/4023-network-and-prereq-setup.pdf and made the necessary change for centos7. I also gave the sandbox and node static ip addresses but that seems ok as i can ssh without password just fine. ... View more

Hi @Geoffrey Shelton Okot. I decided to add a CentOS vm as a node to my cluster instead of the pi. I have configured all the network and prereq steps, installed ambari server on the sandbox and manually installed the ambari agent on the centos vm. I can ssh no problem but it keeps failing at the "Comfirm Hosts" in Ambari with the following error. Registering with the server... Registration with the server failed. Is there any way of knowing what exactly it is failing on as i have been trying this for a couple of days now? Thanks ... View more

Hi, the "choose file" button in ambari allows me to search my host(windows10) filesystem, but i created the /.ssh/id_rsa file within the sandbox. Have i to copy it to my host? ... View more

OK thank you for your time ... View more

I started by creating my own cluster for testing purposes with a laptop as master and three raspberry pis acting as nodes. But when I downloaded the sandbox i realized it would be better to format the three raspberry pis and add them as nodes to the sandbox as it has alot of services built in. I havent added them yet, i was planning on doing all the online tutorials first ... View more
