Rashmi Raghu created MADLIB-976:
-----------------------------------

             Summary: Random Forest - extremely long training time
                 Key: MADLIB-976
                 URL: https://issues.apache.org/jira/browse/MADLIB-976
             Project: Apache MADlib
          Issue Type: Bug
          Components: Module: Random Forest
            Reporter: Rashmi Raghu


When running Random Forest training function on a modest data set it took a long time - much longer than expected or desired. The training data set has around 8000 rows and 400 features. Several models on similar data all took around 40,000 seconds to run.  Each time we used 100 trees and 14 random features selected. Dataset shared offline.
