Yi Zhang updated FLINK-39311:
-----------------------------
Description:
Several tests in DispatcherApplicationTest are flaky, e.g.
Error: 02:53:58 02:53:58.665 [ERROR] Errors:
Error: 02:53:58 02:53:58.665 [ERROR]
DispatcherApplicationTest.testApplicationStatusChange_ThrowsIfDuplicateTerminalStatus:212
» Timeout
The issue can be reproduced locally by running the test repeatedly until
failure. The logs from failed runs contain error messages like:
9553 [ForkJoinPool.commonPool-worker-19] WARN
org.apache.flink.runtime.rpc.MainThreadValidatorUtil [] - Violation of main
thread constraint detected: expected <null> but running in
<Thread[ForkJoinPool.commonPool-worker-19,5,main]>.
