--------------------------------------
Summary: SSH host_proxy has to be fresh
Key: AIRFLOW-6494
URL: https://issues.apache.org/jira/browse/AIRFLOW-6494
Project: Apache Airflow
Issue Type: Bug
Components: contrib
Affects Versions: 1.10.1, 2.0.0
Reporter: Jianchao Yang
AIRFLOW-1762 moved `host_proxy` in contrib/hooks/ssh_hook.py to __init__, which
causes the proxy socket to be closed whenever the SSH client is closed—which
happens every time when exiting `with get_conn() as client`.
The inconsistency between SSH Client and ProxyCommand's lifecycles would result
in "Broken Pipe" error (because the proxy socket has already been closed!) when
the same hook instance is used multiple time (often needed in some custom
operators).
