Konstantin Boudnik updated HADOOP-6332:
---------------------------------------
Attachment: 6332-phase2.fix1.patch
In the secured environment a client should make a privileged RPC call to access a FileSystem
instance from an NN. Thus the fix.
This patch has to be applied on top of 6332-phase2.patch. Not for the inclusion here.

>
> 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
