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,
------------------
