Till Toenshoff commented on MESOS-6340:
---------------------------------------
...and *again* ran into it, this time just like the trap Cody described - a
python based task trying to extract the home-dir of the user "nobody" which had
no home-dir entry in passwd. Is there any reason to not follow what
[~qianzhang] suggested?

> Set HOME for Mesos tasks
> ------------------------
>
> Key: MESOS-6340
> URL: https://issues.apache.org/jira/browse/MESOS-6340
> Project: Mesos
> Issue Type: Bug
> Components: agent, containerization
> Reporter: Cody Maloney
> Priority: Major
> Labels: containerizer
>
> Quite a few programs assume {{$HOME}} points to a user-editable data file
> directory.
> One example is PYTHON, which tries to look up $HOME to find user-installed
> pacakges, and if that fails it tries to look up the user in the passwd
> database which often goes badly (The container is running under the `nobody`
> user):
> {code}
> if i == 1:
> if 'HOME' not in os.environ:
> import pwd
> userhome = pwd.getpwuid(os.getuid()).pw_dir
> else:
> userhome = os.environ['HOME']
> {code}
> Just setting HOME by default to WORK_DIR would enable more software to work
> correctly out of the box. Software which needs to specialize / change it (or
> schedulers with specific preferences), should still be able to set it
> arbitrarily and anything a scheduler explicitly sets should overwrite the
> default value of $WORK_DIR
