----------------------------------------
Summary: BashOperator ignores SIGPIPE in subprocess
Key: AIRFLOW-1745
URL: https://issues.apache.org/jira/browse/AIRFLOW-1745
Project: Apache Airflow
Issue Type: Bug
Components: DagRun
Affects Versions: Airflow 1.8
Reporter: William Pursell
Assignee: William Pursell
In Python 2, subprocesses ignore SIGPIPE (https://bugs.python.org/issue1652).
As a result, a simple bash operator with bash_command = 'yes | head' may never
terminate (depending on the implementation of yes). Airflow should reset the
signal disposition to default.
