----------------------------------
Summary: Fix misleading SparkSubmitOperator and SparkSubmitHook
docstring
Key: AIRFLOW-1319
URL: https://issues.apache.org/jira/browse/AIRFLOW-1319
Project: Apache Airflow
Issue Type: Improvement
Components: contrib
Reporter: Chris Sng
Assignee: Chris Sng
Priority: Trivial
In the community-contributed Spark submit hook and operator, it support
`spark-submit`'s `--files` command line option. The `--files` option is used to
submit file to each executor to be used. A good example of such files are
serialized objects.
However, in both docstrings
(https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/operators/spark_submit_operator.py#L37
and
https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/hooks/spark_submit_hook.py#L36),
it provided `hive-site.xml` as an example. This may mislead less-informed
developers into assuming that Hive configuration files can be submitted to the
cluster in this manner. According to Apache Hive's documentation, hive
configuration files are located in the directory located in the `HIVE_CONF_DIR`
environment variable.
I propose excluding this example from the docstrings.
