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

             Summary: IllegalStateException when empty batch with valid schema is received.
                 Key: DRILL-5854
                 URL: https://issues.apache.org/jira/browse/DRILL-5854
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
    Affects Versions: 1.11.0
            Reporter: Padma Penumarthy
            Assignee: Padma Penumarthy
             Fix For: 1.12.0


When we get a batch with record count 0 and valid schema, the following exception is thrown sometimes.
Problem seem to be that downstream operators are not getting NONE after OK_NEW_SCHEMA with record count 0. 

Error: SYSTEM ERROR: IllegalStateException: Cleanup before finished. 0 out of 1 streams have finished
