+<h2>Changes since Hadoop 2.0.3-alpha</h2>
+<ul>
+<li> <a href="https://issues.apache.org/jira/browse/YARN-470";>YARN-470</a>.
+ Major bug reported by Hitesh Shah and fixed by Siddharth Seth
(nodemanager)<br>
+ <b>Support a way to disable resource monitoring on the NodeManager</b><br>
+ <blockquote>Currently, the memory management monitor's check is disabled
when the maxMem is set to -1. However, the maxMem is also sent to the RM when
the NM registers with it ( to define the max limit of allocate-able resources
).
+
+We need an explicit flag to disable monitoring to avoid the problems caused by
the overloading of the max memory value.</blockquote></li>
+<li> <a href="https://issues.apache.org/jira/browse/YARN-449";>YARN-449</a>.
+ Blocker bug reported by Siddharth Seth and fixed by <br>
+ <b>HBase test failures when running against Hadoop 2</b><br>
+ <blockquote>Post YARN-429, unit tests for HBase continue to fail since
the classpath for the MRAppMaster is not being set correctly.
+Reverting YARN-129 may fix this, but I'm not sure that's the correct solution.
My guess is, as Alexandro pointed out in YARN-129, maven classloader magic is
messing up java.class.path.</blockquote></li>
+<li> <a href="https://issues.apache.org/jira/browse/YARN-443";>YARN-443</a>.
+ Major improvement reported by Thomas Graves and fixed by Thomas Graves
(nodemanager)<br>
+ <b>allow OS scheduling priority of NM to be different than the containers
it launches</b><br>
+ <blockquote>It would be nice if we could have the nodemanager run at a
different OS scheduling priority than the containers so that you can still
communicate with the nodemanager if the containers out of control.
+
+On linux we could launch the nodemanager at a higher priority, but then all
the containers it launches would also be at that higher priority, so we need a
way for the container executor to launch them at a lower priority.
+
+I'm not sure how this applies to windows if at all.</blockquote></li>
+<li> <a href="https://issues.apache.org/jira/browse/YARN-429";>YARN-429</a>.
+ Blocker bug reported by Siddharth Seth and fixed by Siddharth Seth
(resourcemanager)<br>
+ <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>
+<li> <a
href="https://issues.apache.org/jira/browse/MAPREDUCE-5117";>MAPREDUCE-5117</a>.
