Subject Re: mapred timeout
Date Sat, 14 Feb 2009 02:05:47 GMT
In the hadoop-default.xml file:

<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>

- In this job,  we've download a URI from internet and we've read and write
on to Hadoop/HBase as follows:

+ Read some columns in the HBase
+ Write file on to Hadoop
+ Read file from Hadoop

- When I download a site, we have some delay time but total of those
delaytimes are less 60 seconds

please help us!
