huwh opened a new pull request, #22196:
URL: https://github.com/apache/flink/pull/22196
## What is the purpose of the change
Currently the FineGrainedSlotManager is response to slots allocations and
resources request/release. This makes the logical of FineGrainedSlotManager
complicated, So we will move task manager related work from
FineGrainedSlotManager to TaskManagerTracker, which already tracks task
managers but not including request/release.
## Brief change log
*(for example:)*
- *migrate tests to Junit5*
- *move resource allocation/ resource declaration to TaskManagerTracker*
- *move (un-)register task manager to TaskManagerTracker*
- *move task manager idle release check to TaskManagerTracker*
## Verifying this change
- *Add unit tests in FineGrainedTaskManagerTrackerTest*
