这个问题是由于没有启动historyserver引起的，解决办法：
在mapred-site.xml配置文件中添加：
<property>  
        <name>mapreduce.jobhistory.address</name>  
        <value>sjfx:10020</value>  
</property>
 
在namenode上执行命令：mr-jobhistory-daemon.sh start historyserver 
这样在，namenode上会启动JobHistoryServer服务，可以在historyserver的日志中查看运行情况
 
2、14/04/04 17:20:00 INFO mapreduce.Job: Task Id : attempt_1396530865591_0003_m_000011_0, Status : FAILED
出现这个问题可能是由于集群性能瓶颈造成的（IO或网络问题等等）
之前在台式机上虚拟出三个slave的集群，数据量稍微大点就会出现这个问题，后来换了台服务器虚拟出两个slave的集群，没有出现这个问题。
 
3、mapreduce历史作业管理器相关知识（出自：董成西《Hadoop技术内幕 深入解析yarn架构设计与实现原理》）：
为了方便用户查看MapReduce历史作业信息，MRAppMaster提供了一个JobHistoryServer服务，该服务主要由四个子服务组成，具体如下：
a、HistoryClientService.为Web界面展示历史作业信息提供后端实现，它通过调用JobHistory中的相关API获取作业信息，比如提交时间、提交用户、Counter值等，并将这些信息发送到前端。
b、HSAdminServer。管理员可使用“bin/mapred hsadmin” 命令动态更新JobHistoryServer访问和管理权限信息。用户输入该命令后，后端的HSAdminService服务将执行该命令，当前该命令可动态更新以下几种信息：
    ①管理员列表。历史作业查看器的管理员列表（具有启动和停止JobHistoryServer服务、更新权限信息等权限）是通过core-site.xml中的mapreduce.jobhistory.admin.acl属性（默认是“*”,表示任何人都是管理员）设置的。
    ②超级用户组列表。超级用户组信息是通过core-site.xml中的hadoop.proxyuser.groups和hadoop.proxyuser.hosts属性设置的，超级用户组是hadoop引入Kerberos安全机制后，为方便上层应用（比如HBase、Oozie等）访问Hadoop内核服务而新增加的配置项。
    ④用户与用户组映射关系。用户与用户组映射关系是通过core-site.xml中的hadoop.security.group.mapping属性设置的，它需要是一个实现了GroupMappingServiceProvider接口的类，默认实现是ShellBasedUnixGroupsMapping，即采用Linux操作系统的用户和用户组映射关系。
c、AggregatedLogDeletionService。该服务周期性扫描所有历史作业日志目录，如果一个日志目录存放时间超过yarn.nodemanager.log.retain-seconds（单位是秒，默认为3*60*60，即三个小时），则直接将其从HDFS上删除。
d、JobHistory。该服务从HDFS上读取MapReduce历史作业日志，并将其解析成格式化信息，供前端查看。MRAppMaster将执行完成的作业信息保存到mapreduce.jobhistory.intermediate-done-dir指定的目录中，如果用户未设置该属性，则保存到${yarn.app.mapreduce.am.staging-dir}/history/done_intermediate目录中，其中每个作业保存作业配置文件（后缀为.xml）和作业执行日志（后缀为.jhist）两个文件，通过解析作业执行日志，JobHistory能获取作业执行时的所有信息，包括作业提交时间、作业Counter、每个任务提交时间和运行时间、每个任务的Counter等。
