Warning: Overwriting old id attribute = Hang

Member Posts: 14

I have a problem that is driving me crazy. I am using two svms to predict values and then joining followed by a write to csv. Randomly the processes wiill hang after training and in the log I have com.rapidminer.operator.preprocessing.IdTagging apply and then WARNING: Overwriting old attribute...and then nothing. Most of the time, the processes works without problems but not always. This happens more often if I run the processes in sequence using batch files or as subprocesses in parallel.
I have attached a shortened script showing the joins. I would like to run this process daily unattended but this error is making things difficult. Anyone have some ideas on how to avoid this.
Many thanks,
Alex

can you please if the problem still occurs if you disable all the "parallelize XXX" paramters? In some cases, parallelization does not work well and makes the process hang.
Best,
Marius
I have disabled the parallel functions and will see what happens..The odd thing is that it could work fine times in a row and then stop with the warning for no apparent reason. I have several of these to run which I am running at night using batch files. As long as I am asleep, I won't notice the slowdown.
Thanks!
Alex
It seems to be the parallelize training and testing from the sliding window validation. I switched on parallelize main process and I can run on two threads without causing the error.
Thanks for bringing this to my attention.
regards,
Alex
