leixm opened a new pull request, #3655: URL: https://github.com/apache/celeborn/pull/3655
### What changes were proposed in this pull request? Remove some assertions in the "check if fetch failure task another attempt is running or successful" test in SparkUtilsSuite. ### Why are the changes needed? After CELEBORN-2294 added a zombie TaskSetManager check in shouldReportShuffleFetchFailure, the test became flaky due to a race condition. The test calls shouldReportShuffleFetchFailure a second time from the test thread, but by that point the FetchFailed has already been processed by Spark's DAGScheduler — **the TaskSetManager is either marked as zombie** or the task has been removed from taskIdToTaskSetManager. This causes the second call to return false, failing the assertion. ### Does this PR resolve a correctness bug? No. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The affected UT: SparkUtilsSuite - check if fetch failure task another attempt is running or successful. -- This is an automated message from the Apache Git Service.
