[jira] [Updated] (AIRFLOW-1450) FileSensor operator in contrib is always True

["Diogo Franco (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/AIRFLOW-1450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Diogo Franco updated AIRFLOW-1450:
----------------------------------
    Description: 
The *FileSensor* operator in _contrib_ returns True regardless of whether the file exists.

{code:java}
try:
    files = [f for f in walk(full_path)]
except:
    return False
return True
{code}

Iterating over the _walk(full_path)_ generator simply returns an empty list when _full_path_ does not exist, instead of an exception.
