> It is possible to use NetGroups for ACLs. This requires specifying  the config property
org.apache.hadoop.security.ShellBasedUnixGroupsNetgroupMapping as  org.apache.hadoop.security.JniBasedUnixGroupsNetgroupMapping
or org.apache.hadoop.security.ShellBasedUnixGroupsNetgroupMapping.
> The authorization to proxy a user by another user is specified as a list of groups hadoop.proxyuser.<user-name>.groups.
The Group resolution does not work  if we are using NetGroups.
