+
+<li> <a
href="https://issues.apache.org/jira/browse/HADOOP-7960";>HADOOP-7960</a>.
+ Major bug reported by gkesavan and fixed by mattf <br>
+ <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>
+
+<li> <a
href="https://issues.apache.org/jira/browse/HADOOP-7964";>HADOOP-7964</a>.
+ Blocker bug reported by kihwal and fixed by daryn (security, util)<br>
+ <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>
+
+<li> <a
href="https://issues.apache.org/jira/browse/HADOOP-7987";>HADOOP-7987</a>.
+ 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
credentials).</blockquote></li>
+
+<li> <a
href="https://issues.apache.org/jira/browse/HADOOP-7988";>HADOOP-7988</a>.
+ Major bug reported by jnp and fixed by jnp <br>
+ <b>Upper case in hostname part of the principals doesn't work with
kerberos.</b><br>
+ <blockquote>Kerberos doesn't like upper case in the hostname part of
the principals.<br>This issue has been seen in 23 as well as
1.0.</blockquote></li>
+
+<li> <a
href="https://issues.apache.org/jira/browse/MAPREDUCE-3607";>MAPREDUCE-3607</a>.
+ Major improvement reported by tomwhite and fixed by tomwhite (client)<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>
