-----------------------------------
Summary: Set HOME for Mesos tasks
Key: MESOS-6340
URL: https://issues.apache.org/jira/browse/MESOS-6340
Project: Mesos
Issue Type: Bug
Components: containerization, slave
Reporter: Cody Maloney
Assignee: Jie Yu
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
