[BEAM-9631] Flink 1.10 test execution is broken due to premature test cluster shutdown

• Type: Bug

• Priority: P1
• Resolution: Fixed
• Fix Version/s: 2.21.0

Description

Due to a race condition with the test cluster shutdown code, tests may fail because the Flink job result cannot be retrieved when the cluster already has been shut down. This is a Flink 1.10.0 bug which is addressed upstream via FLINK-16705.

If this doesn't get addressed upstream, we may also be able to work around this.
