In Gridmix, in RoundRobinUserResolver, the list of groups for a user obtained from users-list-file
is incorrect
---------------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-2416
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2416
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/gridmix
            Reporter: Ravi Gummadi
            Assignee: Ravi Gummadi


RoundRobinUserResolver.parseUserList() has a bug in obtaining list of groups for each user
--- in the sense that the list is not cleared before obtaining groups list for the next user.
So if the first line has some groups, then from 2nd
line onwards, the validation of "whether the users(in the next lines) are also having group
names in those lines" is useless as the list is already nonempty.

For example, users-list-file content as shown below also is valid as per parseUserList():
------------------
user1,group1
user2,
user3,
user4,
------------------
