Hadoop异常 java.io.IOException: Job status not available

须配置Job History Server相关参数，让Job Client可以读取job最后的执行状态，测试Hadoop版本2.5.0
添加参数vim mapred-site.xml
  <property>
    <name>mapreduce.jobhistory.address</name>
    <value>master.hadoop:10020</value>
  </property>
  <property>
    <name>yarn.app.mapreduce.am.staging-dir</name>
    <value>/tmp/hadoop-yarn/staging</value>
  </property>
  <property>
    <name>mapreduce.jobhistory.intermediate-done-dir</name>
    <value>${yarn.app.mapreduce.am.staging-dir}/history/done_intermediate</value>
  </property>
  <property>
    <name>mapreduce.jobhistory.done-dir</name>
    <value>${yarn.app.mapreduce.am.staging-dir}/history/done</value>
  </property>

修改完成配置后，重新执行任务后正常退出
