>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: nodemanager
>    Affects Versions: 2.7.1

> When the NM launches an AM, the {{ContainerLocalizer}} gets the current user from {{UserGroupInformation}},
which triggers user group mapping, even though the user groups are never accessed.  If secure
LDAP is configured for group mapping, then there are some additional complications created
by the unnecessary group resolution.  Additionally, it adds unnecessary latency to the container
launch time.
> To address the issue, before getting the current user, the {{ContainerLocalizer}} should
configure {{UserGroupInformation}} with a null group mapping service that quickly and quietly
returns an empty group list for all users.
