SQLExecuteQueryOperator to connect to Apache Hive

Use the :class:SQLExecuteQueryOperator<airflow.providers.common.sql.operators.sql> to execute Hive commands in an Apache Hive <https://cwiki.apache.org/confluence/display/Hive/Home>__ database.

.. note:: Previously, HiveOperator was used to perform this kind of operation. After deprecation this has been removed. Please use SQLExecuteQueryOperator instead.

.. note:: Make sure you have installed the apache-airflow-providers-apache-hive package to enable Hive support.

Using the Operator ^^^^^^^^^^^^^^^^^^

Use the conn_id argument to connect to your Apache Hive instance where the connection metadata is structured as follows:

.. list-table:: Hive Airflow Connection Metadata :widths: 25 25 :header-rows: 1

• • Parameter
  • Input
• • Host: string
  • HiveServer2 hostname or IP address
• • Schema: string
  • Default database name (optional)
• • Login: string
  • Hive username (if applicable)
• • Password: string
  • Hive password (if applicable)
• • Port: int
  • HiveServer2 port (default: 10000)
• • Extra: JSON
  • Additional connection configuration, such as the authentication method: {"auth": "NOSASL"}

An example usage of the SQLExecuteQueryOperator to connect to Apache Hive is as follows:

.. exampleinclude:: /../tests/system/apache/hive/example_hive.py :language: python :start-after: [START howto_operator_hive] :end-before: [END howto_operator_hive]

Reference ^^^^^^^^^ For further information, look at:

• Apache Hive Documentation <https://cwiki.apache.org/confluence/display/Hive/Home>__

.. note::

Parameters provided directly via SQLExecuteQueryOperator() take precedence over those specified in the Airflow connection metadata (such as schema, login, password, etc).
