-----------------------------------

             Summary: Atlas fails to lookup users groups if any group names cannot be found
                 Key: ATLAS-2854
                 URL: https://issues.apache.org/jira/browse/ATLAS-2854
             Project: Atlas
          Issue Type: Bug
    Affects Versions: 0.8.1
            Reporter: Sean Roberts


When a user has groups whose names are not available, Atlas hits an exception and fails to find any of the groups resulting in no Atlas access for that user:
{code}
$ id sroberts
uid=1415428167(sroberts) gid=100(users) groups=100(users),1415476164(hdp_admins),1415476163(hdp_users),1414200513,1414548426,1415124193,1414548429
{code}

{code}
## Atlas application.log:
2018-08-31 08:53:31,552 INFO  - [pool-2-thread-25:] ~ SSO login user : sroberts  (AtlasKnoxSSOAuthenticationFilter:182)
2018-08-31 08:53:31,662 WARN  - [pool-2-thread-25:] ~ got exception trying to get groups for user sroberts: id: cannot find name for group ID 1414200513
java.io.IOException: No groups found for user sroberts
{code}

This scenario is common in directory (LDAP/AD) integrated environments.
