使用Yarn(可选)
etc/hadoop/mapred-site.xml<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
etc/hadoop/yarn-site.xml
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
如果不配置会报如下错误：
org.apache.hadoop.yarn.exceptions.InvalidAuxServiceException: The auxService:mapreduce_shuffle does not exist
针对的是hadoop2.7.2+hive2.1.1+sqoop1.4.6
