  JobHistory用来记录已经finished的mapreduce运行日志，日志信息存放于HDFS目录中，默认情况下没有开启此功能，需要在mapred-site.xml中配置并手动启动。

  1、mapred-site.xml配置信息：

<configuration>
<property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
     <description>指定运行mapreduce的环境是yarn，与hadoop1截然不同的地方</description>
</property>

<property>
    <name>mapreduce.jobhistory.address</name>
    <value>xfvm03:10020</value>
    <description>MR JobHistory Server管理的日志的存放位置</description>
</property>

<property>
    <name>mapreduce.jobhistory.webapp.address</name>
    <value>xfvm03:19888</value>
    <description>查看历史服务器已经运行完的Mapreduce作业记录的web地址，需要启动该服务才行</descripti
on>
</property>

<property>
    <name>mapreduce.jobhistory.done-dir</name>
    <value>/opt/big/hadoop-2.7.3/mr-history/done</value>
    <description>MR JobHistory Server管理的日志的存放位置,默认:/mr-history/done</description>
</property>

<property>
    <name>mapreduce.jobhistory.intermediate-done-dir</name>
    <value>/opt/big/hadoop-2.7.3/mr-history/mapred/tmp</value>
    <description>MapReduce作业产生的日志存放位置，默认值:/mr-history/tmp</description>
</property>

<property>
    <name>mapreduce.map.memory.mb</name>
    <value>1024</value>
    <description>每个Map任务的物理内存限制</description>
</property>

<property>
    <name>mapreduce.reduce.memory.mb</name>
    <value>2048</value>
    <description>每个Reduce任务的物理内存限制</description>
</property>
<!-->                                    
<property>
    <name>mapreduce.map.java.opts</name>
    <value>-Xmx1024m</value>
</property>
                            
<property>
    <name>mapreduce.reduce.java.opts</name>
    <value>-Xmx2048m</value>
</property>
<-->
</configuration>

2、启动 jobhistory server

[xfvm@xfvm03 ~]$ mr-jobhistory-daemon.sh start historyserver

问题记录：

3、问题解决

  在yarn-site.xml文件中增加如下属性，并重启jobhistory server

<!--打开HDFS上日志记录功能-->
<property>  
    <name>yarn.log-aggregation-enable</name>  
        <value>true</value>  
</property> 

 

4、yarn-site.xml完整配置如下：
