Hi,
I found out that these logs are stored directly at the TaskNodes.

We need to have them stored over a long time (some months or better a
year). What is a good way of doing that?

With my current knowledge I would write a cron job that picks up all the
files every few minutes.
But I guess thats not the best approach...

Best Regards,
Christian.

Hello,

Jagat Singh

Hi Jagat,
could you give me a short hint which source and Sink I should use?

Because it would be pretty good to have a 1:1 copy from the log folder of
the task nodes. Smth. like:
/<hostname of the
TaskTracker>/var/log/hadoop-0.20-mapreduce/userlogs/job_201303181503_0248/attempt_201303181503_0248_m_000023_0/*

Best Regards,
Christian.
