--------------------------------
Summary: Reshape SchedulerHealth class
Key: YARN-9883
URL: https://issues.apache.org/jira/browse/YARN-9883
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager, yarn
Affects Versions: 3.3.0
Reporter: Adam Antal
The {{SchedulerHealth}} class has some flaws, for example:
- It has no javadoc at all
- All its objects are package-private: they should be private
- The internal maps should be (Concurrent) EnumMaps instead of HashMaps: they
are more efficient in storing Enums
- schedulerHealthDetails only stores the last operation, its name should
reflect that (just like lastSchedulerRunDetails)
