我试图在的文件系统中创建文件夹 HDFS 通过命令

./hadoop fs -mkdir /user/hadoop

结果我收到了以下信息

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

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？
