Please accept this PR that addresses the following issues:
https://issues.apache.org/jira/browse/AIRFLOW-147
In short, the default behavior for the new impala dbapi which is used for the HiveServer2Hook reads a single line at a time when fetchall() is called. This PR provides the option to specify the row batch size in to_csv() and sets the default to 1000.
