Hi, I'm working on analyzing a decision tree in Apache spark 1.2. I've built the tree and I can traverse it to get the splits and impurity. I can't seem to find a way to get which records fall into each node. My goal is to get a count of how accurate each leaf is at identifying the classification. I used MulticlassMetrics with predicting each on to get the accuracy of the tree overall, but I'm not sure how to do this for a branch of the tree. Any input would be appreciated. Thanks.
