-----------------------------------
Summary: SSH Operator errors on commands with no output
Key: AIRFLOW-1813
URL: https://issues.apache.org/jira/browse/AIRFLOW-1813
Project: Apache Airflow
Issue Type: Bug
Reporter: Rob Keevil
The SSH Operator will throw an empty "SSH operator error" when running commands
that do not immediately log something to the terminal. This is due to a call
to stdout.channel.recv when the channel currently has a 0-size buffer, either
because the command has not yet logged anything, or never will (e.g. sleep 5).
A simple check of the buffer size before reading will fix this issue, will link
a PR shortly
