hadoop错误:Task attempt_201405291351_0001_m_000000_0 failed to report status for 744 seconds. Killing!

  在web控制端报错误:

Task attempt_201405291351_0001_m_000000_0 failed to report status for 744 seconds. Killing!

 

原因是由于执行合并索引操作时间较长,所以超过了600秒的时间限制,把这个值改高点就不会报错了。在网上查了一下,
解决的方法:

1、修改job参数
 job.getConfiguration().setInt("mapred.task.timeout", 6000000);  

   2、修改hadoop默认设置,默认值为600s,将value值提高。

<property>  
  <name>mapred.task.timeout</name>  
  <value>600000</value>  
  <description>The number of milliseconds before a task will be terminated if it neither reads an input, 
      writes an output, nor updates its status string.  
  </description>  
</property>
