Subject [jira] Commented: (MAPREDUCE-1376) Support for varied user submission in Gridmix
Date Thu, 01 Apr 2010 05:05:27 GMT

rahul k singh commented on MAPREDUCE-1376:
------------------------------------------

# GridmixTestUtils is not a useful abstraction. Its functionality should remain in/be added
to TestGridmixSubmission
 I feel , it is clean . I have added more code for creation of staging directories in it so
I thought TestGridmixSubmission was getting really big with some reusable components .  I
think we might use those components again in future. Also It is was taking more time get it
back to TestGridmixSubmission , I understand that we could do it later as well but given the
urgency and as there is no harm in pulling some reusable code I am leaving it as it is.


# Since UserResolver can remain an abstract class (no need to extend any groups mapping),
parseUserList can remain there.
parseUserList is only being used by RoundRobinUserResolve to iam leaving the interface as
it is.

> Gridmix currently submits all synthetic jobs as the client user. It should be possible
to map users in the trace to a set of users appropriate for the target cluster.
