-------------------------------------
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.
