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>
