Scott Chen updated MAPREDUCE-1265:
----------------------------------
Description:
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 for example, a blacklisted node.
We have to use the task attempt id to find the TT. This is not very convenient.
It will be nice if we can also log the tasktracker which cauces this error.
This way we can just grep the hostname to quickly find all the relevant error
message.
