Thomas Jungblut updated HAMA-441:
---------------------------------
Attachment: HAMA-441.patch
Added a redirection of the STDOUT and ERR output to distinct log files.
It uses the system property of hamas log dir and puts the tasklogs into a
subdirectory.
Layout is like following:
logs/tasklogs/job_id/task_id.log/err
At first I added a subdirectory for the task-attempt id, but it is the same
like the task id currently, so I tagged this with a todo.
The web interface is a bit more work. We need to add a web server on the grooms
and add the servlet which tails the files.
Then we have to add a job-report site where all tasks are listed.
Should we split this into smaller task? Or I guess nobody else want to do
this?;D

> instead of redirecting the log to the groom.
> Additionally we need to provide a web interface capability to tail the log
> files. Hadoop has similar features.
