【大数据运维】Hadoop开启Yarn的日志监控功能

1.开启JobManager日志

（1）编辑NameNode配置文件${hadoop_home}/etc/hadoop/yarn-site.xml和mapred-site.xml

• 编辑yarn-site.xml

<!-- Site specific YARN configuration properties -->
<configuration>
  <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
  </property>

  <!-- 开启日志聚合 -->
  <!-- 是否启用日志聚集功能 -->
  <property>
    <name>yarn.log-aggregation-enable</name>
    <value>true</value>
  </property>
  <!-- 日志存储时间 -->
  <property>
    <name>yarn.log-aggregation.retain-seconds</name>
    <value>10080</value>
  </property>
  <!--当应用程序运行结束后，日志被转移到的HDFS目录（启用日志聚集功能时有效），如此便可通过appmaster UI查看作业的运行日志。-->
  <property>
    <name>yarn.nodemanager.remote-app-log-dir</name>
    <value>/flink/log</value>
  </property>
  <!-- 日志服务器的地址 -->
  <property>
    <name>yarn.log.server.url</name>
    <value>http://localhost:19888/jobhistory/logs</value>
  </property>
  <!-- 正在运行中的日志在hdfs上的存放路径 -->
  <property>
    <name>mapreduce.jobhistory.intermediate-done-dir</name>
    <value>/history/done_intermediate</value>
  </property>

  <!-- 运行过的日志存放在hdfs上的存放路径 -->
  <property>
    <name>mapreduce.jobhistory.done-dir</name>
    <value>/history/done</value>
  </property>
</configuration>

• 编辑mapred-site.xml

<property>
    <!-- 表示提交到hadoop中的任务采用yarn来运行，要是已经有该配置则无需重复配置 -->
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
</property>
<property>
  <!--日志监控服务的地址，一般填写为namenode机器地址 -->
    <name>mapreduce.jobhistroy.address</name>
    <value>hadoop101:10020</value>
</property>
<!--填写为namenode机器地址-->
<property>
    <name>mapreduce.jobhistroy.webapp.address</name>
    <value>hadoop101:19888</value>
</property>

#复制配置文件到集群的其他机器
scp mapred-site.xml 用户@IP地址:/目标机器文件夹路径
scp yarn-site.xml 用户@IP地址:/目标机器文件夹路径

（3）重启yarn,重启历史服务

./stop-yarn.sh && ./start-yarn.sh

#进入到hadoop的安装目录
cd ${hadoophome}/hadoop/sbin

kill -9 117681 && ./mr-jobhistory-daemon.sh start historyserver

（4）查看服务运行情况

jps

（5）运行flink on yarn

./bin/flink run -m yarn-cluster -c com.lixiang.app.FlinkDemo ./flink-demo-jar-with-dependencies.jar

（6）查看hadoop控制台

2.开启TaskManager日志

        <property>
                <name>javax.jdo.option.ConnectionURL</name>

        </property>
 
        <property>

                <value>com.mysql.jdbc.Driver</value>

        </property>
        <property>
                <name>javax.jdo.option.ConnectionPassword</name>
                <value>123456</value>
        </property>
        <property>
                <name>hive.metastore.schema.verification</name>
                <value>false</value>
        </property>
        <property>
                <name>hive.metastore.event.db.notification.api.auth</name>
                <value>false</value>

        </property>
        <property>
                <name>hive.server2.thrift.bind.host</name>
                <value>ip</value>
        </property>
        <property>
                <name>hive.server2.thrift.port</name>
                <value>10000</value>
        </property>
</configuration>
