Hadoop-名称节点将无法启动

Question

I am trying to run hadoop on ubuntu server. After i start all services and typ JPS I get

hduser@HDFS1:/usr/local/hadoop/etc/hadoop$ jps
5938 DataNode
6133 SecondaryNameNode
6287 ResourceManager
6431 NodeManager
6751 Jps

I believe I should NameNode along with the secondary namne node.

The hdfs-site.xml is

<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>file:/usr/local/hadoop_tmp/hdfs/datanode</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>file:/usr/local/hadoop_tmp/hdfs/datanode</value>
</property>
</configuration>

I have also tried the configuration from another question similar to this with no luck.
