             Summary: Instable Kafka testStartFromKafkaCommitOffsets failures 
on Travis
                 Key: FLINK-7011
                 URL: https://issues.apache.org/jira/browse/FLINK-7011
             Project: Flink
          Issue Type: Bug
          Components: Kafka Connector, Tests
    Affects Versions: 1.3.1, 1.4.0
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai

In general, the test {{testStartFromKafkaCommitOffsets}} implementation is a 
bit of an overkill. Before continuing with the test, it writes some records 
just for the sake of committing offsets to Kafka and waits for some offsets to 
be committed (which leads to the instability), whereas we can do that simply 
using the test base's {{OffsetHandler}}.
