paul-rogers opened a new issue, #12649: URL: https://github.com/apache/druid/issues/12649
`SeekableStreamSupervisorStateTest.testEmitRecordLag` failed in the ARM64 test pass. The [PR in which it failed](https://app.travis-ci.com/github/apache/druid/jobs/573408425) modified nothing in the supervisor area. The same test passes in the other architectures. This same PR passed this test in an earlier build. The change that triggered this build was tiny and in an area of code which the Supervisor does not use. Conclusion: something is flaky. ```text [ERROR] org.apache.druid.indexing.seekablestream.supervisor.SeekableStreamSupervisorStateTest.testEmitBothLag Time elapsed: 2.014 s <<< ERROR! java.util.ConcurrentModificationException at java.base/java.util.ArrayList$ArrayListSpliterator.forEachRemaining(ArrayList.java:1661) at java.base/java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:484) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:474) at java.base/java.util.stream.ReduceOps$ReduceOp.evaluateSequential(ReduceOps.java:913) at java.base/java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:234) at java.base/java.util.stream.ReferencePipeline.collect(ReferencePipeline.java:578) at org.apache.druid.indexing.seekablestream.supervisor.SeekableStreamSupervisorStateTest.filterMetrics(SeekableStreamSupervisorStateTest.java:837) at org.apache.druid.indexing.seekablestream.supervisor.SeekableStreamSupervisorStateTest.testEmitBothLag(SeekableStreamSupervisorStateTest.java:651) ``` -- This is an automated message from the Apache Git Service.
