Vinod K V updated MAPREDUCE-1110:
---------------------------------

    Attachment: MAPREDUCE-1110-20091209.txt

Uploading a new patch now that all blockers are resolved. This also incoporates MAPREDUCE-1075.
A brief summary of what this patch does:
 - Removes the usage of {{JobQueueInfo}} in favor of {{QueueInfo}} throughout mapreduce framework
 - Handles possible NPEs with invalid queue names and adds test to verify that all NPE problems
are handled, a.k.a MAPREDUCE-1075
 - Adds new tests in {{TestQueueManagerWithJobTracker}} to verify the behavior of {{JobTracker}}'s
queue related APIs
 - Sweeps clean all the public API in QueueInfo, JobQuueInfo, Cluster, JobClient, JobTracker
and ClientProtocol
    -- Adds javadoc
    -- Modifies QueueInfo to be a completely read only view, similar to Cluster.
    -- Removes useless APIs that were mostly added in 0.21 to handle deprecated cases and
which are no longer needed. Notably, I've removed {{ClientProtocol.getQueues()}} as we already
have {{getRootQueues()}} and {{getChildQueues()}} which can handle every case possible.

{{JobQueueClient}} is still not tested comprehensively, we need more tests. But I propose
we do it in another JIRA as this one is already stretching itself.
