Hi,
After I failed to run using spark 2.1.0 I did the following:
Downloaded the source code
https://github.com/saurfang/spark-knn/releases/tag/v0.1.1
Built it using spark 1.6.1 (In project/Common.scala and
project/Dependencies.scala I have put 1.6.1 for spark version)
Using version 0.1.1 I am able to run the MNIST example.
Regards,
Kaushik
