<title>IPC Configuration Conflicts with Hadoop</title>
<para>If the Hadoop configuration is loaded after the HBase configuration, and you have
configured custom IPC settings in both HBase and Hadoop, the Hadoop values may overwrite the
HBase values. There is normally no need to change these settings for HBase, so this problem is
an edge case. However, <link
xlink:href="https://issues.apache.org/jira/browse/HBASE-11492">HBASE-11492</link> renames
these settings for HBase to remove the chance of a conflict. Each of the setting names have
been prefixed with <literal>hbase.</literal>, as shown in the following table. No action is
required related to these changes unless you are already experiencing a conflict.</para>
<para>These changes were backported to HBase 0.98.x and apply to all newer versions.</para>
