HST server placement
You should designate one node in the HDP cluster as the HST server, so that this component can efficiently consolidate the data collected by all HST agents into a single downloadable file (referred to as a bundle). Any of the management nodes, such as Ambari Server, Metrics Server, and so on, are good choices for the HST server placement.
Administrators and each HST agent in the cluster must have network access to the HST server. This connectivity is required for agents to consolidate their data and for Hadoop administrators to download completed bundles. For a full list of ports and a data flow diagram, refer to SmartSense ports and traffic flow documentation.
