Re: Creating a custom trace file using Rumen
Arun,

Rumen doesn't support this. You have to manually edit the trace file.

Rumen is a tool which converts Hadoop MapReduce logs into a standard format. The Rumen trace and the jobhistory files are identical in some sense (information content wise).
It would be helpful to understand your usecases first.

Hi guys !
I was trying to use Rumen to generate trace files. I have few queries :
Q1> Is there any way to create a new trace file from job history logs with
custom set of split locations ?
Q2> Can we create new trace files from existing trace files with new values
for the attributes like preferred locations ?
Q3> How can i add new attributes / fields (which are not in job history
logs) to the job or the tasks in the trace ? (or)
Is there any way to generate trace with extra fields ?
Can anyone help me in this regard ?
Thanks,
Arun
