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).

Although it is not a requirement, when you install HST without using Ambari, you should provide the HST server node with passwordless root access, through SSH, to all HST agent nodes in the cluster. This access enables single-click capture through the HST server web UI in a non-Ambari environment. If the web UI is not available, you can still perform captures from the CLI.

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.
