nicoweidner opened a new pull request #16654:
URL: https://github.com/apache/flink/pull/16654
## What is the purpose of the change
This pull request changes
JobVertexThreadInfoTrackerTest#testCachedStatsCleanedAfterCleanupInterval so
that unfortunate timings no longer lead to potential failures.
Before, if the provided JobVertexThreadInfoStats object was evicted from
cache before we could fetch it, the test would fail. Now, we do not fetch it at
all, but simply verify that one item was evicted from cache.
## Brief change log
- *JobVertexThreadInfoTracker can be instantiated with a provided Cache
instance. If none is provided to JobVertexThreadInfoTrackerBuilder, it will use
an identical one to that used so far*
- *testCachedStatsCleanedAfterCleanupInterval uses this to configure the
cache to track statistics and verify the eviction*
- *unnecessary wait times in testCachedStatsCleanedAfterCleanupInterval and
testCachedStatsUpdatedAfterRefreshInterval are reduced
## Verifying this change
*(Please pick either of the following options)*
This change is already covered by existing tests, such as
