Airflow manages execution dependencies among jobs (known as operators in Airflow parlance) in the DAG, and programmatically handles job failures, retries, and alerting. py; We will create a new operator from BaseOperator where we will define execute to use two existing Operators from. Operators are divided into 3 types: Action operators that perform some action such as executing a Python function or submitting a Spark Job. - Analyze and optimization performance and stable of system - General debugging, bug fixing and refactoring, code review. Example of operators could be an operator that runs a Pig job (PigOperator), a sensor operator that waits for a partition to land in Hive (HiveSensorOperator), or one that moves data from Hive to MySQL (Hive2MySqlOperator).
