您好目前我正在运行hadoop 2.4.1。我创建使用eclipse一个简单的Java程序DefaultMapperClass.java并打包成ex1.jarHadoop不与资源管理器通信
当我尝试使用该命令将通过Hadoop的外壳来调用这个程序，
**hadoop jar /home/Maddy/ex1.jar DefaultMapperClass hdfs://localhost/users/root/input/Hadoop.txt hdfs://localhost/users/root/output**
我得到下面的输出Hadoop的外壳
**[[email protected] Maddy]# hadoop jar /home/Maddy/ex1.jar DefaultMapperClass hdfs://localhost/users/root/input/Hadoop.txt hdfs://localhost/users/root/output
14/09/05 19:26:35 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

14/09/05 19:26:35 INFO client.RMProxy: Connecting to ResourceManager at localhost/127.0.0.1:8032
[[email protected] Maddy]#**
看起来像Hadoop的外壳试图连接到资源管理器，但不成功，但没有错误消息
MAPR ED-site.xml文件：
**<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>**
纱-site.xml中：
**<configuration>
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
<value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>
<property>
<name>yarn.resourcemanager.address</name>
<value>localhost:8032</value>
</property>
<property>
<name>yarn.resourcemanager.scheduler.address</name>
<value>localhost:8030</value>
</property>
<property>
<name>yarn.resourcemanager.resource-tracker.address</name>
<value>localhost:8031</value>
</property>
</configuration>**
缺少什么吗？为什么在尝试连接资源管理器后终止执行？
