I looked at the below examples:
https://builds.apache.org/job/kafka-pr-jdk14-scala2.13/149/testReport/junit/org.apache.kafka.streams.integration/GlobalKTableEOSIntegrationTest/shouldKStreamGlobalKTableLeftJoin_exactly_once_beta_/
https://builds.apache.org/job/kafka-pr-jdk11-scala2.13/6017/testReport/junit/org.apache.kafka.streams.integration/EosIntegrationTest/shouldNotViolateEosIfOneTaskFailsWithState_exactly_once_beta__2/
https://builds.apache.org/job/kafka-pr-jdk11-scala2.13/6017/testReport/junit/org.apache.kafka.streams.integration/GlobalKTableEOSIntegrationTest/shouldKStreamGlobalKTableLeftJoin_exactly_once_beta__2/
And also reproduced the flakiness locally after about 180 runs, and the failed
one did not have any obvious different traces compared with the successful ones.
