+ <b>move up to Jackson 1.8.8</b><br>
+ <blockquote>I see that hadoop-core still depends on Jackson 1.0.1 -but
that project is now up to 1.8.2 in releases. Upgrading will make it easier for
other Jackson-using apps that are more up to date to keep their classpath
consistent.<br><br>The patch would be updating the ivy file to pull in the
later version; no test</blockquote></li>

+ <b>0.20: Allow block reports to proceed without holding FSDataset
lock</b><br>
+ <blockquote>As disks are getting larger and more plentiful, we're
seeing DNs with multiple millions of blocks on a single machine. When page
cache space is tight, block reports can take multiple minutes to generate.
Currently, during the scanning of the data directories to generate a report,
the FSVolumeSet lock is held. This causes writes and reads to block, timeout,
etc, causing big problems especially for clients like HBase.<br><br>This JIRA
is to explore some of the ideas originally discussed in
HADOOP-458...</blockquote></li>

+ <b>NamenodeMXBean does not account for svn revision in the version
information</b><br>
+ <blockquote>Unlike the jobtracker where both the UI and jmx information
report the version as "x.y.z, r<svn revision", in case of the
namenode, the UI displays x.y.z and svn revision info but the jmx output only
contains the x.y.z version.</blockquote></li>

<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
