Hadoop2.7.3 完全分布模式下datanode节点启动不起来..求支招

[D小調]

core-site.xml的配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://s0:9000</value>
</property>
<property>
<name>io.file.buffer.size</name>
<value>131072</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/moclick/hadoop/tmp</value>
</property>
</configuration>
</configuration>

hdfs-site.xml的配置如下:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>dfs.namenode.secondary.http-address</name>
<value>s3:50090</value>
</property>
<property>
<name>dfs.replication</name>
<value>2</value>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>file:/home/moclick/hadoop/hdfs/name</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>file:/home/moclick/hadoop/hdfs/data</value>
</property>
</configuration>

datanode节点的异常信息如下：
java.io.IOException: Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.

实在找不到解决办法，求大佬们支招~
