SparkSqlHook

This hook is a wrapper around the spark-sql binary. It requires that the

class airflow.providers.apache.spark.hooks.spark_sql.SparkSqlHook(sql, conf=None, conn_id=default_conn_name, total_executor_cores=None, executor_cores=None, executor_memory=None, keytab=None, principal=None, master=None, name='default-name', num_executors=None, verbose=True, yarn_queue=None)[source]

Bases: airflow.hooks.base.BaseHook

This hook is a wrapper around the spark-sql binary. It requires that the “spark-sql” binary is in the PATH.

Parameters
  • sql (str) – The SQL query to execute

  • conf (Optional[str]) – arbitrary Spark configuration property

  • conn_id (str) – connection_id string

  • total_executor_cores (Optional[int]) – (Standalone & Mesos only) Total cores for all executors (Default: all the available cores on the worker)

  • executor_cores (Optional[int]) – (Standalone & YARN only) Number of cores per executor (Default: 2)

  • executor_memory (Optional[str]) – Memory per executor (e.g. 1000M, 2G) (Default: 1G)

  • keytab (Optional[str]) – Full path to the file that contains the keytab

  • master (Optional[str]) – spark://host:port, mesos://host:port, yarn, or local (Default: The host and port set in the Connection, or "yarn")

  • name (str) – Name of the job.

  • num_executors (Optional[int]) – Number of executors to launch

  • verbose (bool) – Whether to pass the verbose flag to spark-sql

  • yarn_queue (Optional[str]) – The YARN queue to submit to (Default: The queue value set in the Connection, or "default")

conn_name_attr = conn_id[source]
default_conn_name = spark_sql_default[source]
conn_type = spark_sql[source]
hook_name = Spark SQL[source]
get_conn(self)[source]

Returns connection for the hook.

run_query(self, cmd='', **kwargs)[source]

Remote Popen (actually execute the Spark-sql query)

Parameters
  • cmd (str) – command to append to the spark-sql command

  • kwargs (Any) – extra arguments to Popen (see subprocess.Popen)
