[jira] [Commented] (AIRFLOW-2122) SSHOperator throws an error
[ https://issues.apache.org/jira/browse/AIRFLOW-2122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16369049#comment-16369049 ]
Ash Berlin-Taylor commented on AIRFLOW-2122:
--------------------------------------------
How have you defined the {{ssh_node}} connection? I think you (quite rightly) specified one of {{compress}} or {{no_host_key_check}} as a boolean, but it needs to be a string.
The work around for you is to specify it as a string.
The fix is to make the SSHHook cope with string or boolean for these parameters..
