Not failing today. It does have some flakes, but not this one from what I can see.

Wait, I read it wrong. This is exactly the flake.

org.apache.beam.sdk.transforms.ParDoLifecycleTest.testTeardownCalledAfterExceptionInStartBundleStateful is tracked in #21266

Maybe this should just track the GroupByKey one? It does look quite flaky:

Updated the description so this just tracks the GroupByKeyTest failure. Let's use https://github.com/apache/beam/issues/21266 to track the ParDoLifecycleTest flake

This is the top flaky test in the suite.

As much as I want to work on this, that hasn't happened in the last two weeks and I don't see it happening this year so I'm going to unassign it.
