Date Fri, 07 Jul 2017 22:11:00 GMT
Artiom created AIRFLOW-1387:
-------------------------------

             Summary: Logging causes UnicodeEncodeError on simple bash task.
                 Key: AIRFLOW-1387
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1387
             Project: Apache Airflow
          Issue Type: Bug
          Components: logging, operators, scheduler
    Affects Versions: Airflow 1.8
         Environment: Ubuntu 16.04 vagrant machine
            Reporter: Artiom
            Assignee: Artiom


Encountered an issue breaking my DAGs after switching from 1.7.1.3
The problem appears on my vagrant default ubuntu 16.04 machine. The output of locale command.
LANG=en_US.UTF-8
LANGUAGE=en_US:
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
To replicate I created a DAG with single bash operator task that runs 'download.sh'
The code for download.sh is pretty simple:

{code:java}
wget ftp://anonymous:guest@ftp.debian.org/debian/README.mirrors.txt

{code}
It breaks on the first backquote.
