----------------------------------
Hi [~kmarton],
Recently I started to work on YARN-3890. May I ask whether you want to resolve
this issue in the near future?
Working in parallel on the same piece of code would probably cause one of us to
handle lot of conflicts when rebasing.
> 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
> Assignee: Kinga Marton
> Priority: Minor
>
> 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)
