Eric Yang updated YARN-7782:
----------------------------
Description: In YARN-4266, the recommendation was to use -u [uid]:[gid]
numeric values to enforce user and group for the running user. In YARN-7430,
the user remapping is default to true, but yarn-default.xml is still set to
false. (was: In YARN-4266, the recommendation was to use -u [uid]:[gid]
numeric values to enforce user and group for the running user. In YARN-6623,
this translated to --user=test --group-add=group1. The code no longer enforce
group correctly for launched process.
In addition, the implementation in YARN-6623 requires the user and group
information to exist in container to translate username and group to uid/gid.
For users on LDAP, there is no good way to populate container with user and
group information. )
> Enable user re-mapping for Docker containers in yarn-default.xml
