[jira] [Created] (FLINK-8398) Stabilize flaky
KinesisDataFetcherTests
Tzu-Li (Gordon) Tai created FLINK-8398:
------------------------------------------
Summary: Stabilize flaky KinesisDataFetcherTests
Key: FLINK-8398
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
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.
