Upgrade HDP Stack With Per Node Method.
Steps
1) Prepare and save component states.
2) Setup prerequisites for background jobs.
3) Start long-running background jobs for all components.
4) Upgrade core components from bottom to top.
For each service, does:
4a) Upgrade service.
4b) Run smoke tests for all components.
4c) Check number of all background jobs.
5) After all components are upgraded, run another set of tests.
6) Repeat same process for non-core components.
7) Upgrade clients of components which were upgraded earlier.
8) Upgrade client-only components.
9) After all components are upgraded, run smoke tests.
10) Stop long running jobs.
11) Look for failed and kill jobs.
12) Verify outputs of successful jobs.
13) Finalize all states.
