Alexey Romanenko commented on BEAM-3317: ---------------------------------------- [~iemejia] Well, actually this is two different errors happened in the same test - original assert failure and other from your log (there are two different asserts in that test, they are similar but not the same). Running thousands of times this test suite in IDEA I've managed to reproduce only once (!) the fail from your attached log but not from original Jira description. [~pawel.kaczmarczyk] don't you have any idea why it can fail but so rare and how we can reproduce it? > KinesisReaderTest is Flaky due to overadvanced watermarks > --------------------------------------------------------- > > Key: BEAM-3317 > URL: https://issues.apache.org/jira/browse/BEAM-3317 > Project: Beam > Issue Type: Bug > Components: io-java-kinesis > Reporter: Thomas Groh > Assignee: Alexey Romanenko > Priority: Critical > Labels: flake, sickbay > Attachments: kinesisflakytests2.txt > > > https://builds.apache.org/job/beam_PreCommit_Java_GradleBuild/392/testReport/junit/org.apache.beam.sdk.io.kinesis/KinesisReaderTest/watermarkAdvancesWhenEnoughRecordsReadRecently/ > org.junit.ComparisonFailure: expected:<[-290308-12-21T19:59:05.225]Z> but > was:<[1970-01-01T00:00:01.000]Z> -- This message was sent by Atlassian JIRA (v7.6.3#76005)
