Konstantin Boudnik commented on HADOOP-6332:
--------------------------------------------

bq. system-test.xml need not go in common
While I'm mostly agree that {{system-test.xml}} shouldn't be in common (a 
config file in common shouldn't have any knowledge about upstream 
dependencies), I am reluctant to split it. The problem with the split as I see 
it is that both copies of the file in HDFS and MR will mostly contains the same 
information with some minor differences. However, considering the exposing 
upstream dependencies is worst I will make the split and post new patch shortly.

bq.  jar-test-system ant target
Thanks for catching this one. Looks like we have the same problem in original 
implementation and it has been missed. Will fix it.

> Hadoop would benefit from having a large-scale, automated, test-framework. 
> This jira is meant to be a master-jira to track relevant work.
> ----
> The proposal is a junit-based, large-scale test framework which would run 
> against _real_ clusters.
> There are several pieces we need to achieve this goal:
> # A set of utilities we can use in junit-based tests to work with real, 
> large-scale hadoop clusters. E.g. utilities to bring up to deploy, start & 
> stop clusters, bring down tasktrackers, datanodes, entire racks of both etc.
> # Enhanced control-ability and inspect-ability of the various components in 
> the system e.g. daemons such as namenode, jobtracker should expose their 
> data-structures for query/manipulation etc. Tests would be much more relevant 
> if we could for e.g. query for specific states of the jobtracker, scheduler 
> etc. Clearly these apis should _not_ be part of the production clusters - 
> hence the proposal is to use aspectj to weave these new apis to 
> debug-deployments.
> ----
> Related note: we should break up our tests into at least 3 categories:
> # src/test/unit -> Real unit tests using mock objects (e.g. HDFS-669 & 
> MAPREDUCE-1050).
> # src/test/integration -> Current junit tests with Mini* clusters etc.
> # src/test/system -> HADOOP-6332 and it's children
