Vinod Kumar Vavilapalli updated MAPREDUCE-2986:
-----------------------------------------------
Component/s: test
mrv2
Affects Version/s: 0.23.0
Fix Version/s: 0.23.0
Looked at the patch. Mostly looks fine, some minor comments:
- Disable TestMRJobs.testSleepJobWithSecurityOn(), it won't work on Jenkins.
- Undo the changes in ShuffleHandler.Shuffle w.r.t port, it was done like that
to avoid findBugs warnings.
- Wrap around lines longer than 80 chars.
- ContainerManager.start(): Move the log "ContainerManager started at" to the
end of the method before super.start(). Similarly move the log message in
ResourceLocalizationService.start() to the end.
- MiniYarnCluster:
-- You can remove the field nodeManagerWrapper completely
-- Remove unused imports.
> Multiple node managers support for the MiniYARNCluster

> The current MiniYARNCluster can only support 1 node manager, which is not
> enough for the full test purposes.
> Would like to have a simulator that can support multiple node managers as the
> real scenario. This might be beneficial for hadoop users, testers and
> developers.
