      Description

      The FlinkKinesisConsumerTest.testSourceSynchronization seems to be unstable on Travis. It fails with

      [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)
      

      https://api.travis-ci.org/v3/job/541845510/log.txt

      While looking 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.
