Can you check what is the value of "mapred.task.timeout" in hadoop-default.xml. If there is no such value try setting the property as -
<property> <name>mapred.task.timeout</name> <value>800000</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> Seems like a timeout error. - Ashwanth Kumar On Thu, Jan 19, 2012 at 3:00 AM, Ahmed Abdeen Hamed <ahmed.elma...@gmail.com > wrote: > Hello friends, > > I am new to Apache MapReduce.
