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

             Summary: FileSourceFunction doesn't respect InputFormat's life cycle methods
                 Key: FLINK-3796
                 URL: https://issues.apache.org/jira/browse/FLINK-3796
             Project: Flink
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.0.1, 1.0.0, 1.0.2
            Reporter: Maximilian Michels
            Assignee: Maximilian Michels
             Fix For: 1.1.0


The {{FileSourceFunction}} wraps {{InputFormat}} but doesn't execute its life cycle functions correctly.

1) It doesn't call {{close()}} before reading the next InputSplit via {{open(InputSplit split)}}.

2) It calls {{close()}} even if no InputSplit has been read (and thus open(..) hasn't been called previously).
