------------------------------------------
Some info to help folks get started:
It should be fairly trivial to ask for n resources, launch containers and then get them to run.
Some of the tests like [TestFifoScheduler|http://svn.apache.org/viewvc/hadoop/common/trunk/hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/test/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/fifo/TestFifoScheduler.java?view=markup], and the mock [Application|http://svn.apache.org/viewvc/hadoop/common/trunk/hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/test/java/org/apache/hadoop/yarn/server/resourcemanager/Application.java?view=markup] used for testing should help give you an idea too.
The interfaces you'd most like be concerned with are:
[ClientRMProtocol|http://svn.apache.org/viewvc/hadoop/common/trunk/hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/ClientRMProtocol.java?view=markup] - Protocol for job-client (launching program from gateway) to talk to RM to launch a new application i.e. application master itself
