Currently, there are many REST endpoints in Yunikorn which provide a bunch of useful information about applications, nodes, node utilization, etc.
However, it requires many round trips to retrieve all of these. Also, it is often beneficial to periodically log detailed state information.
The scope of this ticket is:
- Introduce new REST endpoint which collects and returns all info which is currently available separately
- Refactor code (extract DAO generating methods)
- Add new REST endpoints which enables/disables periodic state logging
