+==== Client Configuration
+In version 1.6.0, Accumulo includes a new type of configuration file known as a client
+configuration file. One problem with the traditional "site.xml" file that is prevalent
+through Hadoop is that it is a single file used by both clients and servers. This makes

+The client configuration file is a subset of the information stored in accumulo-site.xml
+meant only for consumption by clients of Accumulo. By default, Accumulo checks a number
+of locations for a client configuration by default:
+* +${ACCUMULO_CONF_DIR}/client.conf+
+* +/etc/accumulo/client.conf+
