[jira] [Created] (AIRFLOW-147) HiveServer2Hook.to_csv() writing one row at a time and causing excessive logging

Michael Musson created AIRFLOW-147:
--------------------------------------

             Summary: HiveServer2Hook.to_csv() writing one row at a time and causing excessive logging
                 Key: AIRFLOW-147
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-147
             Project: Apache Airflow
          Issue Type: Bug
          Components: hooks
    Affects Versions: Airflow 1.7.0
            Reporter: Michael Musson
            Priority: Minor


The default behavior of fetchmany() in impala dbapi (which airflow switched to recently) is to return a single row at a time. This causes HiveServer2's to_csv() method to output one row of logging for each row of data in the results.
