.. py:class:: PinotAdminHook(conn_id: str = 'pinot_admin_default', cmd_path: str = 'pinot-admin.sh', pinot_admin_system_exit: bool = False)

   Bases: :class:`airflow.hooks.base.BaseHook`

   This hook is a wrapper around the pinot-admin.sh script.
   For now, only small subset of its subcommands are implemented,
   which are required to ingest offline data into Apache Pinot
   (i.e., AddSchema, AddTable, CreateSegment, and UploadSegment).
   Their command options are based on Pinot v0.1.0.

   Unfortunately, as of v0.1.0, pinot-admin.sh always exits with
   status code 0. To address this behavior, users can use the
   pinot_admin_system_exit flag. If its value is set to false,
   this hook evaluates the result based on the output message
   instead of the status code. This Pinot's behavior is supposed
   to be improved in the next release, which will include the
   following PR: https://github.com/apache/incubator-pinot/pull/4110

   :param conn_id: The name of the connection to use.
   :type conn_id: str
   :param cmd_path: The filepath to the pinot-admin.sh executable
   :type cmd_path: str
   :param pinot_admin_system_exit: If true, the result is evaluated based on the status code.
                                   Otherwise, the result is evaluated as a failure if "Error" or
                                   "Exception" is in the output message.
