[Solved] You have this Airflow DAG snippet:dbt_run = BashOperator(task_id='dbt_run', bash_command='dbt run') dbt_test = BashOperator(task_id='dbt_test', bash_command='dbt test') dbt_test.... | dbt

dbt - Production Deployment

You have this Airflow DAG snippet:

dbt_run = BashOperator(task_id='dbt_run', bash_command='dbt run')
dbt_test = BashOperator(task_id='dbt_test', bash_command='dbt test')
dbt_test.set_downstream(dbt_run)

Why does the dbt_run task never execute?

AAirflow requires PythonOperator for dbt commands, not BashOperator

BThe bash_command syntax is incorrect for running dbt commands

CThe task IDs are not unique and cause a conflict

DThe task dependency is reversed; <code>dbt_test</code> should run after <code>dbt_run</code>

Step-by-Step Solution

Solution:

Step 1: Analyze task dependencies
The code uses dbt_test.set_downstream(dbt_run), which means dbt_run runs after dbt_test.
Step 2: Understand intended order
Typically, dbt_run should execute before dbt_test because tests validate the run results.
Step 3: Identify the error
The dependency is reversed, so dbt_run never triggers since dbt_test is not scheduled first.
Final Answer:
The task dependency is reversed; dbt_test should run after dbt_run -> Option D
Quick Check:
Check task dependencies for correct order [OK]

Quick Trick: Check if task dependencies reflect intended execution order [OK]

Common Mistakes:

MISTAKES

Confusing set_upstream and set_downstream methods
Assuming BashOperator cannot run dbt commands
Overlooking task ID uniqueness
