core-site.xml 文件中的端口

Question

我尝试通过命令在HDFS的文件系统中创建文件夹

./hadoop fs -mkdir /user/hadoop

结果我收到了以下消息

13/02/17 09:45:50 INFO ipc.Client: Retrying connect to server: one/192.168.1.8:9000. Already tried 0 time(s).
13/02/17 09:45:51 INFO ipc.Client: Retrying connect to server: one/192.168.1.8:9000. Already tried 1 time(s).

Bad connection to FS. command aborted. exception: Call to one/192.168.1.8:9000 failed on connection exception: java.net.ConnectException: Connection refused 

在 /export/hadoop-1.0.1/conf/core-site.xml 文件中指定了以下内容：

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->

<configuration>

<property>
 <name>fs.default.name</name>
 <value>hdfs://192.168.1.8:9000</value>
</property>

</configuration>

想指定——我指定的端口是否正确？如果不存在，请说明需要什么？

似乎 hadoop 守护进程没有运行。与 jps 核实
