Hi all, I'm observing this exception using/integrating Brisk with Mahout.


*Brisk* currently works perfectly with all hadoop stack (Hadoop, hive, pig).


I read a similar thread:
http://comments.gmane.org/gmane.comp.apache.mahout.user/6757 which makes me
think it can be hadoop related.


We are using *0.20.203* (Yahoo distribution)


Does this exception look familiar to you all ?


It happens after running the 3 jobs for the Example: *Clustering of
Synthetic control data*.
