Bugs: RANGER-3024
https://issues.apache.org/jira/browse/RANGER-3024
Repository: ranger
Description
-------
GET API /service/xusers/lookup/users returns List of String object which
contains username. But it also traverse through groupUser list while populating
view object VXUser. When there are large number of users and group_users data
in database; it takes longer time to respond if we set request parameter
pageSize=1000 or more. This causes performance issue.
So created a new method lookupXUsers which will search for users based on
searchCriteria and map user entity to view object. It will not traverse through
groupUsers.

Testing
-------
GET request for /service/xusers/lookup/users API returns response
instantaneously even with request parameter pageSize=50000.
Tested with following stats :
select count(*) from x_user;
50052
select count(*) from x_group_users;
500056
