解决方案：
在mapred-site.xml文件中添加mapreduce所需要用到的classpath。

<property>
   <name>mapreduce.application.classpath</name>
   <value><hadoop跟目录>/share/hadoop/mapreduce/*, <hadoop跟目录>/share/hadoop/mapreduce/lib/*</value>
</property>

解决方案
（老版本）在mapred-site.xml文件中添加

<property>
   <name>mapreduce.jobhistory.address</name>
   <value>kylin1:10020</value>
</property>
<property>
   <name>mapreduce.jobhistory.webapp.address</name>
   <value>kylin1:19888</value>
</property>

（新版本） yarn-site.xml 中添加

</property>
<!--新版本指定文件-->
    <property>
        <name>yarn.resourcemanager.webapp.address.rm1</name>
        <value>kylin1</value>
    </property>
    <property>
        <name>yarn.resourcemanager.scheduler.address.rm2</name>
        <value>kylin2</value>
    </property>
<property>

报错：
Container [pid=8794,containerID=container_1552484587522_0002_01_000005] is running 431118848B beyond the 'VIRTUAL' memory limit. Current usage: 51.4 MB of 1 GB physical memory used; 2.5 GB of 2.1 GB virtual memory used. Killing container.

解决方案：
hadoop 配置文件 yarn-site.xml 中添加

<property>
  <name>yarn.nodemanager.vmem-check-enabled</name>
  <value>false</value>
</property>
