[info] - SPARK-47148: AQE should avoid to submit shuffle job on cancellation *** FAILED *** (6 seconds, 92 milliseconds)
[info]   "Multiple failures in stage materialization." did not contain "coalesce test error" (AdaptiveQueryExecSuite.scala:939)

The root cause is that AdaptiveSparkPlanExec.cleanUpAndThrowException throws two types of exceptions. When there are multiple errors, _LEGACY_ERROR_TEMP_2235 is thrown. We need to handle this too in the test case.

+1, LGTM

[cloud-fan]

For Multiple failures in stage materialization, we put each stage's failure into Exception#suppressed. Shall we find the coalesce test error in the suppressed errors?

[dongjoon-hyun]

Sure, @cloud-fan .

Thank you, @LuciferYang and @cloud-fan . Could you review once more? I addressed all comments.

[dongjoon-hyun]

Could you review this too, @viirya ? This is a little very flaky in these days in CIs. Multiple times a day.

[dongjoon-hyun]

Thank you, @LuciferYang , @cloud-fan , @viirya . Let me merge this to stabilize our CIs.
