Yes, it is like this:
<configuration>
<property>
<name>dfs.datanode.data.dir</name>
<value>file:///home/ubuntu/hadoop-2.3.0/hdfs/datanode</value>
<description>Comma separated list of paths on the local filesystem of a
DataNode where it should store its blocks.</description>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>file:///home/ubuntu/hadoop-2.3.0/hdfs/namenode</value>
<description>Path on the local filesystem where the NameNode stores the
namespace and transaction logs persistently.</description>
</property>
</configuration>
