Burak Yavuz updated SPARK-2916: ------------------------------- Description: While running any of the regression algorithms with gradient descent, the treeAggregate blows up after several iterations. Observed on EC2 cluster with 16 nodes, matrix dimensions of 1,000,000 x 5,000 In order to replicate the problem, use aggregate multiple times, maybe over 50-60 times. was: While running any of the regression algorithms with gradient descent, the treeAggregate blows up after several iterations.
