--------------------------------------
Summary: Flaky test:
org.apache.spark.scheduler.TaskSchedulerImplSuite
Key: SPARK-28584
URL: https://issues.apache.org/jira/browse/SPARK-28584
Project: Spark
Issue Type: Bug
Components: Tests
Affects Versions: 3.0.0
Reporter: Marcelo Vanzin
This is another of those tests that don't seem to fail in PRs here, but fail
more often than we'd like in our build machines. In this case it fails in
several different ways, e.g.:
{noformat}
org.scalatest.exceptions.TestFailedException:
Map(org.apache.spark.scheduler.TaskSetManager$$EnhancerByMockitoWithCGLIB$$c676cf51@412f9d43
-> 1550579875956) did not contain key

Or:
{noformat}
The code passed to eventually never returned normally. Attempted 40 times over
503.217543 milliseconds. Last failure message: tsm.isZombie was false.

There's a race condition in the test that can cause these different failures.
