<b>capacity-scheduler config missing from yarn-test artifact</b><br>
<blockquote>MiniYARNCluster and MiniMRCluster are unusable by downstream
projects with the 2.0.3-alpha release, since the capacity-scheduler
configuration is missing from the test artifact.
hadoop-yarn-server-tests-3.0.0-SNAPSHOT-tests.jar should include the default
capacity-scheduler configuration. Also, this doesn't need to be part of the
default classpath - and should be moved out of the top level directory in the
dist package.</blockquote></li>

+ <b>FifoScheduler incorrectly checking for node locality</b><br>
+ <blockquote>In the FifoScheduler, the assignNodeLocalContainers method is
checking if the data is local to a node by searching for the nodeAddress of the
node in the set of outstanding requests for the app. This seems to be
incorrect as it should be checking hostname instead. The offending line of
code is 455:
+
+application.getResourceRequest(priority, node.getRMNode().getNodeAddress());
+
+Requests are formated by hostname (e.g. host1.foo.com) whereas node addresses
are a concatenation of hostname and command port (e.g. host1.foo.com:1234)
+
+In the CapacityScheduler, it's done using hostname. See
LeafQueue.assignNodeLocalContainers, line 1129
+
+application.getResourceRequest(priority, node.getHostName());
+
+Note that this bug does not affect the actual scheduling decisions made by the
FifoScheduler because even though it incorrect determines that a request is not
local to the node, it will still schedule the request immediately because it's
rack-local. However, this bug may be adversely affecting the reporting of job
status by underreporting the number of tasks that were node
local.</blockquote></li>
