Konstantin Boudnik updated HADOOP-6332:
---------------------------------------
Attachment: 6332-phase2.patch
This is the second portion of main Herriot functionality including some of the
tests already linked to the JIRA.
This patch isn't for commit to the Apache 0.20 branch, but is the reference
material for coming forward port to the trunk (0.22). During the forward port
process the tests (about 7 of them or so) from this patch will be taken out and
finally replaced with the patches attached to the linked JIRAs.

> 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
