hadoop2.5.1集群搭建：（四）配置historyServer

1.在mapred-site中配置
<property>
        <name>mapreduce.jobhistory.address</name>
        <value>hadoop2-2:10020</value>
        <description>MapReduce JobHistory Server host:port.    Default port is 10020.</description>
    </property>
    <property>
        <name>mapreduce.jobhistory.webapp.address</name>
        <value>hadoop2-2:19888</value>
        <description>MapReduce JobHistory Server Web UI host:port. Default port is 19888.</description>
    </property>
<property>
        <name>mapreduce.jobhistory.intermediate-done-dir</name>
        <value>/home/hadoop/opt/hadoop/tmp/mr_history</value>
        <description>Directory where history files are written by MapReduce jobs.</description>
    </property>
    <property>
        <name>mapreduce.jobhistory.done-dir</name>
        <value>/home/hadoop/opt/hadoop/tmp/mr_history</value>
        <description>Directory where history files are managed by the MR JobHistory Server.</description>
    </property>

2.在yarn-site.xml中配置
<property> 
    <name>yarn.log-aggregation-enable</name> 
    <value>true</value> 
</property>  




3.复制到集群的其他节点

4.重新启动yarn平台
  sbin/stop-yarn.sh
  sbin/start-yarn.sh

  最后执行sbin/mr-jobhistory-daemon.sh start historyserver
