MapReduce任務運行到running job卡住

改變hadoop里的yarn-site.xml文件

舊版本

<configuration>
<!-- Site specific YARN configuration properties -->
<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.resource-tracker.address</name>
  <value>192.168.2.140:8025</value>
</property>
<property>
  <name>yarn.resourcemanager.scheduler.address</name>
  <value>192.168.2.140:8030</value>
</property>
<property>
  <name>yarn.resourcemanager.address</name>
  <value>192.168.2.140:8040</value>
</property>
</configuration>

 

更改后

<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>
</configuration>
