---------------------------------

             Summary: Make SinkITCase more stable
                 Key: FLINK-19936
                 URL: https://issues.apache.org/jira/browse/FLINK-19936
             Project: Flink
          Issue Type: Sub-task
          Components: API / DataStream
            Reporter: Guowei Ma


In the streaming execution mode there are two uncertain things:
 # The order of receiving the checkpoint complete.(`Committer` receive first or `GlobalCommitter` receive first)
 # Whether the operator can accept the last checkpoint

These lead to the `SinkITCase` unstable. 

This pr resolves the `SinkITCase`s unstable by these two uncertain stuff.
