config hadoop files (one node cluster)

In the newest hadoop versions like 2.7 what are the appropriate and necessary configurations?

I'm reading some documentation to try install hadoop just in one node using a virtual machine but I'm not sure that I'm doing this correctly.

I'm configuring core-site.xml

<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</vaue>
</property>
</configuration>

And hdfs-site.xml

  <configuration>
    <property>
    <name>dfs.replication</name>
    <value>1</value>
    </property>
    </configuration>

Theese are the unique configuration files needed in newest versions and they are ok?

And also, mapred-site.xml to configure job tracker is necessary in the newest versions?

When I start the cluster it starts but the secondary namenode appears with 0.0.0.0 it is normal?

0.0.0.0: starting secondarynamenode, logging to /usr/local/hadoop-2.7.1/logs/hadoop-hadoopadmin-secondarynamenode-hadoop.out

It seems to be ok. You can check this for all the configurations needed to set up a Single Node Cluster.
