title: Why is the task inside my DAG not running?
body: <p>I have scheduled my airflow DAGs to run, every DAG has one task inside of them. When the DAGs run, the tasks inside them don't get executed.

  <p>Here's my code for the same <strong><em>(I am trying to SSH into an EC2 server and run a bash command)</em></strong>:</p>
  
  <pre><code>from datetime import timedelta, datetime
  from airflow import DAG
  from airflow.contrib.operators.ssh_operator import SSHOperator
  
  
  default_args = {
      'owner': 'airflow',
      'depends_on_past': False,
      'email': ['removed@example.com'],
      'email_on_failure': True,
      'email_on_retry': True,
      'start_date': datetime.now() - timedelta(days=1),
      'retries': 1,
      'retry_delay': timedelta(minutes=5),
  }
  
  dag = DAG(dag_id='back_fill_reactivated_photo_dimension',
            default_args=default_args,
            schedule_interval='55 * * * *',
            dagrun_timeout=timedelta(seconds=120))
  
  t1_bash = """
  /usr/local/bin/dp/database_jobs/run_py.sh "backfill_photo_dim_reactivated.py"
  """
  
  t1 = SSHOperator(
      ssh_conn_id='ssh_aws_ec2',
      task_id='backfill_photo_dim',
      command=t1_bash,
      dag=dag)
  </code></pre>
  
  <p>The Airflow UI shows the DAG to be in the running state but the actual task inside the DAG never runs, am I missing something in my code?

  <p>Also, is there a way to force run a DAG regardless of it's CRON schedule?</p>
