Yuan Mei commented on FLINK-17949:
----------------------------------
Based on the failure reported in this Jira, the failure occurs amongst three
tests: `testSerDeIngestionTime`, `testSerDeEventTime` and
`testSerDeProcessingTime`; they share the same code path of `testRecordSerDe`.
So I extract these three tests (based on master 0c20f25fd5a4351) to re-run on
my local azure.
*I’ve run more than 3000 tests for about 11 hours in total without a single
test failure on azure.*
Here is a bit more detail:
* 200 runs; with 3 tests mentioned above; finished in 3 hours; total 600 tests
[https://dev.azure.com/mymeiyuan/Flink/_build/results?buildId=39&view=results]
* 270 runs; with 3 tests mentioned above; canceled after 4 hours by azure;
total 810 tests
[https://dev.azure.com/mymeiyuan/Flink/_build/results?buildId=40&view=results]
* 149 runs; with all the original tests in KafkaShuffleITCase; canceled after
4 hours by azure; total 1639 tests
[https://dev.azure.com/mymeiyuan/Flink/_build/results?buildId=41&view=results]
Besides, this ticket seems not to report any new failure cases after 6/10, so
it is possible that the fix of [FLINK-17327] Fix Kafka Producer Resource Leaks
#12589 (merged around 6/10) also fix this? Kafka versions are also bumped in
[FLINK-17327].
I guess this should provide enough confidence to say that KafkaShuffle test
cases are stable now.
If the ticket does not report any new failures, I will close this ticket.
