Fixing blank charts on ambari home page (Hortonworks Data Platform)

I created a 4 node container based (Proxmox LXC) Hortonworks Data Platform 2.5 Hadoop cluster recently and all went well apart from all the charts on the Ambari homepage were blank or showing “N/A”, like this:

An outline of the environment:

  • 4 node cluster of LXC containers on Proxmox host
  • Centos 7 Linux OS
  • Nodes are called bishdp0[1-4], all created from same template and identical configuration
  • All containers are on 192.168.1.0/24 (more...)
