Hadoop INFO ipc.Client：重试连接到服务器localhost / 127.0.0.1:9000(Hadoop INFO ipc.Client: Retrying connect to server localhost/127.0.0.1:9000)

 我阅读了有关Hadoop的HDFS配置问题的其他帖子。 但是，它们都没有帮助。 所以，我发布了我的问题。 我按照本教程了解了hadoop v1.2.1。 当我运行hadoop fs -ls命令时，我遇到了这个错误： 
 
16/08/29 15:20:35 INFO ipc.Client: Retrying connect to server:   localhost/127.0.0.1:9000. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS)
 
 我的core-site.xml文件是： 
 
<configuration>
<property>
  <name>fs.default.name</name>
    <value>hdfs://localhost:9000</value>
</property>

<property>
  <name>hadoop.tmp.dir</name>
    <value>/mnt/miczfs/hadoop/tmp/${user.name}</value>
</property>
</configuration>
 
 另外，我的hdfs-site.xml文件如下： 
 
<configuration>
<property>
 <name>dfs.replication</name>
 <value>1</value>
    </property>
<property>
   <name>dfs.name.dir</name>
    <value>/mnt/miczfs/hadoop/hdfs/${user.name}/namenode</value>
</property>
 <property>
    <name>dfs.secondary.http.address</name>
    <value>localhost:0</value>
 </property>
<property>
  <name>dfs.data.dir</name>
    <value>/mnt/miczfs/hadoop/hdfs/${user.name}/datanode</value>
</property>
<property>
   <name>dfs.datanode.address</name>
   <value>localhost:0</value>
</property>
<property>
   <name>dfs.datanode.http.address</name>
   <value>localhost:0</value>
</property>
<property>
   <name>dfs.datanode.ipc.address</name>
   <value>localhost:0</value>
</property>
</configuration>
 
 和/ etc / hosts是这样的： 
 
127.0.0.1   localhost localhost.localdomain localhost4  localhost4.localdomain4
::1         localhost localhost.localdomain localhost6    localhost6.localdomain6
 172.31.1.1      micrasrelmond.local micrasrelmond #Generated-by-micctrl
 172.31.1.1      mic0.local mic0 #Generated-by-micctrl
 
 如果有可能，请帮助我。 谢谢 

I read other posts about the HDFS configuration problem with Hadoop. However, none of them was helpful. So, I post my question. I followed this tutorial for hadoop v1.2.1. When I am running hadoop fs -ls command I've got this error:
 
16/08/29 15:20:35 INFO ipc.Client: Retrying connect to server:   localhost/127.0.0.1:9000. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS)
 
My core-site.xml file is:
 
<configuration>
<property>
  <name>fs.default.name</name>
    <value>hdfs://localhost:9000</value>
</property>

<property>
  <name>hadoop.tmp.dir</name>
    <value>/mnt/miczfs/hadoop/tmp/${user.name}</value>
</property>
</configuration>
 
Also, my hdfs-site.xml file is as follow:
 
<configuration>
<property>
 <name>dfs.replication</name>
 <value>1</value>
    </property>
<property>
   <name>dfs.name.dir</name>
    <value>/mnt/miczfs/hadoop/hdfs/${user.name}/namenode</value>
</property>
 <property>
    <name>dfs.secondary.http.address</name>
    <value>localhost:0</value>
 </property>
<property>
  <name>dfs.data.dir</name>
    <value>/mnt/miczfs/hadoop/hdfs/${user.name}/datanode</value>
</property>
<property>
   <name>dfs.datanode.address</name>
   <value>localhost:0</value>
</property>
<property>
   <name>dfs.datanode.http.address</name>
   <value>localhost:0</value>
</property>
<property>
   <name>dfs.datanode.ipc.address</name>
   <value>localhost:0</value>
</property>
</configuration>
 
and the /etc/hosts is this:
 
127.0.0.1   localhost localhost.localdomain localhost4  localhost4.localdomain4
::1         localhost localhost.localdomain localhost6    localhost6.localdomain6
 172.31.1.1      micrasrelmond.local micrasrelmond #Generated-by-micctrl
 172.31.1.1      mic0.local mic0 #Generated-by-micctrl
 
If it is possible, please help me. Thanks
