[jira] [Created] (IOTDB-3629) TimeJoinOperator may cause Source handle is blocked exception

Yuan Tian created IOTDB-3629:
--------------------------------

             Summary: TimeJoinOperator may cause Source handle is blocked exception
                 Key: IOTDB-3629
                 URL: https://issues.apache.org/jira/browse/IOTDB-3629
             Project: Apache IoTDB
          Issue Type: Bug
            Reporter: Yuan Tian
            Assignee: Yuan Tian


TimeJoinOperator should wait for all children have data, then it can do the calculation. However, currently in its isBlocked() method, we only return one child's block state. If this child's block state is unblocked. Then TimeJoinOperator will do its calculation which is incorrect because other children may be in block state.
