airflow任务运行抛出jinja2.exceptions.TemplateNotFound

这是由于airflow使用了jinja2作为模板引擎导致的一个陷阱，当使用bash命令的时候，尾部必须加一个空格:

• herebash_commandBashOperator

t2 = BashOperator( task_id=‘sleep‘, bash_command="/home/batcher/test.sh", // This fails with `Jinja template not found` error #bash_command="/home/batcher/test.sh ", // This works (has a space after) dag=dag)
