Till Rohrmann created FLINK-12768: ------------------------------------- Summary: FlinkKinesisConsumerTest.testSourceSynchronization unstable on Travis Key: FLINK-12768 URL: https://issues.apache.org/jira/browse/FLINK-12768 Project: Flink Issue Type: Bug Components: Connectors / Kinesis Affects Versions: 1.9.0 Reporter: Till Rohrmann Fix For: 1.9.0
The {{FlinkKinesisConsumerTest.testSourceSynchronization}} seems to be unstable on Travis. It fails with {code} [ERROR] testSourceSynchronization(org.apache.flink.streaming.connectors.kinesis.FlinkKinesisConsumerTest) Time elapsed: 10.031 s <<< FAILURE! java.lang.AssertionError: Expected: iterable containing ["1", <Watermark @ -4>] but: No item matched: <Watermark @ -4> at org.apache.flink.streaming.connectors.kinesis.FlinkKinesisConsumerTest.testSourceSynchronization(FlinkKinesisConsumerTest.java:950) {code} https://api.travis-ci.org/v3/job/541845510/log.txt While locking into the problem, I noticed that the test case takes 1 second to execute on my machine. I'm wondering whether this really needs to take this long. Moreover, the test code contains {{Thread.sleeps}} and uses {{Whiteboxing}} which we should avoid. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
