Posted 2020-09-12 ChavinKing

在yarn-site.xml配置文件中添加如下内容：

##开启日志聚集功能
        <property>
                <name>yarn.log-aggregation-enable</name>
                <value>true</value>
        </property>
##日志保存7天（单位秒）
        <property>
                <name>yarn.log-aggregation.retain-seconds</name>
                <value>600000</value>
        </property>

重启resourcemanager、nodemanager和historyserver守护进程：
            sbin/yarn-daemon.sh start|stop resourcemanager
            sbin/yarn-daemon.sh start|stop nodemanager
            或者
            sbin/start-yarn.sh
            sbin/stop-yarn.sh
           
            sbin/mr-jobhistory-daemon.sh start|stop historyserver
