regarding clustering using mahout 0.7...NEED YOUR VALUABLE RESPONSES
Hi all
I am trying to run mean-shift clustering algorithm using mahout 0.7
on a input
file of 2.7GB choosing some values for T1,T2..
after 1 or 2 iterations the job is getting finished...but folder with name
clusters-n-final(which contains the final clusters) is not being formed....
What does this mean??..ITS A BIT URGENT.....NEED YOUR VALUABLE RESPONSES....
Thanks in advance

Check your job logs too. With improper values for T1 & T2 your
map/reduce tasks could be getting OME failures that are stopping the
overall job before it converges. Try running Canopy to get values of T
that do not run out of memory. Then try those T values with mean shift.

The clustering is not converging.
Can you try to run with max number of iterations specified?
