| Hive Metastore Connection |
| ========================= |
| |
| The Hive Metastore connection type enables the Hive Metastore Integrations. |
| |
| Authenticating to Hive Metastore |
| -------------------------------- |
| |
| Authentication with the Hive Metastore through `Apache Thrift Hive Server |
| <https://cwiki.apache.org/confluence/display/Hive/HiveServer>`_ |
| and the `hmsclient |
| <https://pypi.org/project/hmsclient/>`_. |
| |
| |
| Default Connection IDs |
| ---------------------- |
| |
| All hooks and operators related to the Hive Metastore use ``metastore_default`` by default. |
| |
| Configuring the Connection |
| -------------------------- |
| |
| Host (optional) |
| The host of your Hive Metastore node. It is possible to specify multiple hosts as a comma-separated list. |
| |
| Port (optional) |
| Your Hive Metastore port number. |
| |
| Extra (optional) |
| Specify the extra parameters (as json dictionary) that can be used in Hive Metastore connection. |
| The following parameters are all optional: |
| |
| * ``auth_mechanism`` |
| Specify the mechanism for authentication. Default is ``NOSASL``. |
| * ``kerberos_service_name`` |
| Specify the kerberos service name. Default is ``hive``. |
| |
| |
| When specifying the connection in environment variable you should specify |
| it using URI syntax. |
| |
| Note that all components of the URI should be URL-encoded. |
| |
| For example: |
| |
| .. code-block:: bash |
| |
| export AIRFLOW_CONN_METASTORE_DEFAULT='hive-metastore://hive-metastore-node:80?auth_mechanism=NOSASL' |
