Hi I am executing the following recommendation engine using Spark ML
https://aws.amazon.com/blogs/big-data/building-a-recommendation-engine-with-spark-ml-on-amazon-emr-using-zeppelin/ When I am trying to save the model, the application hungs and does't respond. Any pointers to find where the problem is? Is there any blog/doc which guides us to efficiently debug Spark applications? Thanks & Regards Mukund
