[GitHub] [beam] Abacn opened a new issue, #26301: [Failing Test]: beam_PreCommit_Java_PVR_Flink_Batch stuck
Abacn opened a new issue, #26301:
URL: https://github.com/apache/beam/issues/26301
### What happened?
There is possibility that this precommit stuck and timing out after 4 hour. It is not obvious which test is timing out. Having downloaded the raw log in the jenkins node, it is found that the stucking test is `CombineTest.basicTests#testCombinePerKeyLambda` at least for https://ci-beam.apache.org/job/beam_PreCommit_Java_PVR_Flink_Batch_Cron/9111/
### Issue Failure
Failure: Test is flaky
### Issue Priority
Priority: 2 (backlog / disabled test but we think the product is healthy)
