Hadoop Pseudo-Disrtibuted Cluster Namenode fails to start

I am attempting to set up a hadoop pseudo-distributed cluser on CentOS 6.5. The version of Hadoop that I am using is 0.20. I am also using Apache Pig version 0.12.1.

I modified the following conf files:

core-site.xml 

    <property>
            <name>fs.default.name</name>
            <value>hdfs://localhost:8020</value>
    </property>

hdfs-site.xml

<configuration>
<property>
    <name>fs.default.name</name>
    <value>1</value>
</property>

<property>
    <name>dfs.permissions</name>
       <value>false</value>
</property>
</configuration>

mapred-site.xml

<configuration>
    <property>
            <name>mapred.job.tracker</name>
            <value>127.0.0.1:8021</value>
    </property>
</configuration>

So, after I configured the appropriate files, I issued the command hadoop namenode -format as well as sh start-all.sh. However, after running the jps command, I see that the namenode, secondaryname, and datanode all run, but only for a short time. Looking at the log files, I see this:

2014-11-28 20:32:59,434 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode:     java.io.IOException: Call to /0.0.0.1:8020 failed on local exception: java.net.SocketException: Invalid argument
at org.apache.hadoop.ipc.Client.wrapException(Client.java:775)

How would I go about fixing this issue?

You may find that you need to use the hostname of the machine instead of localhost or 127.0.0.1.

You should specify your namenode with the appropriate port

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