spark on yarn cluster查看日志

[hadoop@hadoop001 shell]$ yarn logs -applicationId application_1420997455428_0005
15/01/12 04:34:51 INFO client.RMProxy: Connecting to ResourceManager at /0.0.0.0:8032
/tmp/logs/hadoop/logs/application_1420997455428_0005does not exist.
Log aggregation has not completed or is not enabled.
原因是聚合日志没有开启

解决如下：

[hadoop@hadoop001 hadoop]$ vi yarn-site.xml
  <!--开启聚合日志--> 
    <property>
        <name>yarn.log-aggregation-enable</name>
        <value>true</value>
    </property>
      <!--设置聚合日志放置的位置--> ///tmp/logs是hdfs分布式系统上面的，自己创建自定义的文件夹
    <property>
        <name>yarn.nodemanager.remote-app-log-dir</name>
        <value>/tmp/logs</value>
    </property>
    <!--设置聚合日志存放的时间，单位为秒，会自动移除-->
    <property>
        <name>yarn.log-aggregation.retain-seconds</name>
  <value>3600</value>
    </property>

配置完yarn-site.xml之后重启节点，再次查看日志

[hadoop@hadoop001 shell]$ yarn logs -applicationId application_1420997455428_0005
15/01/12 09:53:43 INFO client.RMProxy: Connecting to ResourceManager at /0.0.0.0:8032

注：1.查看某个应用的日志

yarn logs -applicationId application_1420997455428_0005

2.查看某个应用的状态

yarn application -status application_1420997455428_0005

3.杀掉某个应用
（直接在UI界面或者是终端kill掉任务都是不对的，该任务可能还会继续执行下去，所以要用如下命令才算完全停止该应用的执行）

yarn application -kill application_1420997455428_0005
