>                 URL: https://issues.apache.org/jira/browse/FLINK-8398
>             Project: Flink
>          Issue Type: Bug
>          Components: Kinesis Connector, Tests
>    Affects Versions: 1.4.0, 1.5.0
>            Reporter: Tzu-Li (Gordon) Tai
>            Assignee: Tzu-Li (Gordon) Tai
>            Priority: Major
>             Fix For: 1.5.0, 1.4.1
>
>
> The unit tests in {{KinesisDataFetcherTest}} have very flaky implementations. They rely
on on thread sleeps to wait for a certain operation to happen, which can easily miss and cause
tests to fail.
> Although there isn't any reports of consistent failures on these tests yet (as far as
I am aware of),  they can easily surface in the future.
