Shimin Yang created FLINK-11084:
-----------------------------------

             Summary: Incorrect ouput after two successive split and select
                 Key: FLINK-11084
                 URL: https://issues.apache.org/jira/browse/FLINK-11084
             Project: Flink
          Issue Type: Bug
          Components: Streaming
            Reporter: Shimin Yang
            Assignee: Shimin Yang
             Fix For: 1.5.6, 1.6.3, 1.8.0, 1.7.1


The second OutputSelector of two successive split and select are actually not rely on the first one. They are in the same array of OutputSelector in DirectedOutput.

For example.

outputSelector1 => \{“name1” or ”name2“}

outputSelector2 => \{”name3“ or “name4”}

resultStream = dataStream.split(outputSelector1).select("name2").split(outputSelector2).select("name3")

expectedResult for input \{StreamRecord1}:

outputSelector1 => \{”name1“}

outputSelector2 => \{”name3“}

resultStream => {}

actualResult:

resultStream => \{StreamRecord1}
