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

             Summary: CoRecordReader Does Not Read Events From Both Inputs When No Elements Arrive
                 Key: FLINK-2290
                 URL: https://issues.apache.org/jira/browse/FLINK-2290
             Project: Flink
          Issue Type: Bug
          Components: Streaming
            Reporter: Aljoscha Krettek


When no elements arrive the reader will always try to read from the same input index. This means that it will only process elements form this input. This could be problematic with Watermarks/Checkpoint barriers.
