yarn开启日志输出设置
在yarn-site.xml文件中添加如下配置：
<property>
<name>yarn.log-aggregation-enable</name>
<value>true</value>
</property>
<property>
<name>yarn.nodemanager.remote-app-log-dir</name>
<value>/oracle/hadoop/logs/yarn</value>
</property>
<property>
<name>yarn.log-aggregation.retain-seconds</name>
<value>259200</value>
</property>
<property>
<name>yarn.log-aggregation.retain-check-interval-seconds</name>
<value>3600</value>
</property>之后同步到集群各个子节点，重启yarn即可。
