Avery,
There is no other logs than that, at least to my knowledge.
Is it removes logs automatically, because I have the same type of logs
mentioned but only for a job done the 16th of April (the one concerned was
the 13th).
I cannot launch any more the process, I had to change the hadoop version
Etienne,
There should be one task log per task. Do you have all the tasks logs?
It looks like this one failed because another one failed.

Avery,
I attach the file, indeed it looks more interesting that the others. There
is a null pointer exception:
15 MapAttempt TASK_TYPE="MAP" TASKID="task_201204121825_0001_m_02"
TASK_ATTEMPT_ID="attempt_201204121825_0001_m_02_0" TASK_STATUS="FAILED"
FINISH_TIME="13342517 07662" HOSTN
Etienne, the task tracker logs are not what I meant, sorry for the
confusion. Every task produces it's own output and error log. That is
likely where we can find the issue. Likely a task failed, and the task
logs should say why.

Hi Etienne,
Thanks for your questions. Giraph uses map tasks to run its master and
workers. Can you provide the task output logs? It looks like your
workers failed to report status for some reason and we need to find out
why. The datanode logs can't help us here.
