Subject [jira] [Commented] (YARN-8241) MRAppMaster fails when using UID:GID pair within docker container
Date Mon, 07 May 2018 18:23:00 GMT

Suma Shivaprasad commented on YARN-8241:
----------------------------------------

This would also be useful for Spark applications on docker which do a similar user lookup.

the MRAppMaster fails for docker containers if there is no additional user lookup strategy
(e.g. bind-mounting /var/run/nscd or /etc/passwd). We need a better solution so that users
can still run even if they are not known inside of the container by name
