In addition to @mqureshi, if you are looking for upgrade proccess.

There are two methods for upgrading HDP with Ambari: Rolling Upgrade and Express Upgrade.

  • A Rolling Upgrade orchestrates the HDP upgrade in an order that is meant to preserve cluster operation and minimize service impact during upgrade. This process has more stringent prerequisites (particularly regarding cluster high availability configuration) and can take longer to complete than an Express Upgrade.
  • An Express Upgrade orchestrates the HDP upgrade in an order that will incur cluster downtime but with less stringent prerequisites.

Here is the link for the upgrade procces
