我已经在我的笔记本电脑上设置了一个hadoop单一模式。信息：Ubuntu12.10，JDK1.7Oracle，从.deb文件安装hadoop。位置：/etc/hadoop/usr/share/hadoop
我在/usr/share/hadoop/templates/conf/core-site.xml中有config，我添加了2个属性

<property>
  <name>hadoop.tmp.dir</name>
  <value>/app/hadoop/tmp</value>
  <description>A base for other temporary directories.</description>
</property>

<property>
  <name>fs.default.name</name>
  <value>hdfs://localhost:9000</value>
  <description>The name of the default file system.  A URI whose
  scheme and authority determine the FileSystem implementation.  The
  uri's scheme determines the config property (fs.SCHEME.impl) naming
  the FileSystem implementation class.  The uri's authority is used to
  determine the host, port, etc. for a filesystem.</description>
</property>

在hdfs-site.xml中

<property>
  <name>dfs.replication</name>
  <value>1</value>
  <description>Default block replication.
  The actual number of replications can be specified when the file is created.
  The default is used if replication is not specified in create time.
  </description>
</property>

在mapred-site.xml中

<property>
  <name>mapred.job.tracker</name>
  <value>localhost:9001</value>
  <description>The host and port that the MapReduce job tracker runs
  at.  If "local", then jobs are run in-process as a single map
  and reduce task.
  </description>
</property>

当我开始命令的时候hduser@sepdau：~$start-all.sh

starting namenode, logging to /var/log/hadoop/hduser/hadoop-hduser-namenode-sepdau.com.out
localhost: starting datanode, logging to /var/log/hadoop/hduser/hadoop-hduser-datanode-sepdau.com.out
localhost: starting secondarynamenode, logging to /var/log/hadoop/hduser/hadoop-hduser-secondarynamenode-sepdau.com.out

localhost: starting tasktracker, logging to /var/log/hadoop/hduser/hadoop-hduser-tasktracker-sepdau.com.out

但当我用jps查看流程时

hduser@sepdau:~$ jps
13725 Jps

当我停下来的时候

hduser@sepdau:~$ stop-all.sh
no jobtracker to stop
localhost: no tasktracker to stop
no namenode to stop
localhost: no datanode to stop
localhost: no secondarynamenode to stop

在我的主机文件中

hduser@sepdau:~$ cat /etc/hosts

127.0.0.1       localhost
127.0.1.1   sepdau.com

# The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

从文件：localhost主文件：localhost
这是一些日志

我使用root用户，但它有同样的问题
我错在这里了。如何使用hadoop插件连接到eclipse。谢谢你的预付款
