+     <b>Port HADOOP-5203 to branch-1, build version comparison is too restrictive</b><br>
+     <blockquote>hadoop services should not be using the build timestamp to verify
version difference in the cluster installation. Instead it should use the source checksum
as in HADOOP-5203.<br>  </blockquote></li>

+     <b>Deadlock in class init.</b><br>
+     <blockquote>After HADOOP-7808, client-side commands hang occasionally. There are
cyclic dependencies in NetUtils and SecurityUtil class initialization. Upon initial look at
the stack trace, two threads deadlock when they hit the either of class init the same time.</blockquote></li>

+     Major improvement reported by devaraj and fixed by jnp (security)<br>
+     <b>Support setting the run-as user in unsecure mode</b><br>
+     <blockquote>Some applications need to be able to perform actions (such as launch
MR jobs) from map or reduce tasks. In earlier unsecure versions of hadoop (20.x), it was possible
to do this by setting user.name in the configuration. But in 20.205 and 1.0, when running
in unsecure mode, this does not work. (In secure mode, you can do this using the kerberos

+     <b>Upper case in hostname part of the principals doesn&apos;t work with kerberos.</b><br>

+     <b>Port missing new API mapreduce lib classes to 1.x</b><br>
+     <blockquote>There are a number of classes under mapreduce.lib that are not present
in the 1.x series. Including these would help users and downstream projects using the new
MapReduce API migrate to later versions of Hadoop in the future.<br><br>A few
examples of where this would help:<br>* Sqoop uses mapreduce.lib.db.DBWritable and mapreduce.lib.input.CombineFileInputFormat
(SQOOP-384).<br>* Mahout uses mapreduce.lib.output.MultipleOutputs (MAHOUT-822).<br>*
HBase has a backport of mapreduce.lib.partition.InputSampler ...</blockquote></li>
