             Summary: Stream operators need to differentiate between close() 
and dispose()
                 Key: FLINK-2647
                 URL: https://issues.apache.org/jira/browse/FLINK-2647
             Project: Flink
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 0.10
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 0.10


Currently, operators make no distinction between closing (which needs to emit 
remaining buffered data) and disposing (releasing resources).

In case of a failure, we want to only release the resources, and not attempt to 
send pending buffered data.

Effectively, streaming operators need to implement these methods then:
  - open()
  - processRecord()
  - processWatermark()
  - close()
  - dispose()
