> When task attempt receive an error, TaskInProgress will log the task attempt id and diagnosis string in the JobTracker log.
> Ex:
> 2009-xx-xx 23:50:45,994 INFO org.apache.hadoop.mapred.TaskInProgress: Error from attempt_2009xxxx_xxxx_r_000009_1: Error: java.lang.OutOfMemoryError: Java heap space
> 2009-xx-xx 22:53:53,146 INFO org.apache.hadoop.mapred.TaskInProgress: Error from attempt_2009xxxx_xxxx_m_000478_0: Task attempt_2009xxxx_xxxx_m_000478_0 failed to report status for 601 seconds. Killing!
> When we want to debug a machine or a job. We have to use the task attempt id to find these information.
> It will be much more convenient if  we can just log them together.
> This way we can just grep the jobId or hostname to quickly find all the relevant error message.
