--------------------------------
Summary: Linux native container executor segfaults if default
banned user detected
Key: YARN-2847
URL: https://issues.apache.org/jira/browse/YARN-2847
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.5.0
Reporter: Jason Lowe
The check_user function in container-executor.c can cause a segmentation fault
if banned.users is not provided but the user is detected as one of the default
users. In that scenario it will call free_values on a NULL pointer.
