 <h3 id="table-namespaces">Table namespaces</h3>
 <p>Administering an Accumulo instance with many tables is cumbersome.  To ease this,
<a href="https://issues.apache.org/jira/browse/ACCUMULO-802" title="Table namespaces">ACCUMULO-802</a>
introduced table namespaces which allow tables to be grouped into logical collections.  This
allows configuration and permission changes to made to a namespace, which will apply to all
of its tables.  Example use cases are ... TODO</p>

-<p>Accumulo has not offered a way to make atomic row changes until now.  Accumulo now
supports atomic test and set row operations.  <a href="https://issues.apache.org/jira/browse/ACCUMULO-1000"
title="Conditional Mutations">ACCUMULO-1000</a> added conditional mutations and a
conditional writer.  A conditional mutation has tests on columns that must pass before any
changes are made.  These test are executed in server processes while a row lock is held.

in a Map Reduce job.  TODO is there more to say about this, if not maybe move to one-liners.</p>
 <h3 id="locality-groups-in-memory">Locality groups in memory</h3>
 <p>In cases where a very small amount of data is stored in a locality group one would
expect fast scans over that locality group.  However this was not always the case because
recently written data stored in memory was not partitioned by locality group.  Therefore if
a table had 100GB of data in memory and 1MB of that was in locality group A, then scanning
A would have required reading all 100GB.  <a href="https://issues.apache.org/jira/browse/ACCUMULO-112"

and partitions data by locality group as its written.</p>

 <h3 id="service-ip-addresses">Service IP addresses</h3>
 <p>Previous versions of Accumulo always used IP addresses internally.  This could be
problematic in virtual machine environments where IP addresses change.  In <a href="https://issues.apache.org/jira/browse/ACCUMULO-1585"
title="Use FQDN/verbatim data from config files">ACCUMULO-1585</a> this was changed,
now the accumulo uses the exact hostnames from its config files for internal addressing.
