Colin Beckingham created SPARK-16768:
----------------------------------------
Summary: pyspark calls incorrect version of logistic regression
Key: SPARK-16768
URL: https://issues.apache.org/jira/browse/SPARK-16768
Project: Spark
Issue Type: Bug
Components: MLlib, PySpark
Environment: Linux openSUSE Leap 42.1 Gnome
Reporter: Colin Beckingham
Fix For: 2.1.0
PySpark call with Spark 1.6.2 "LogisticRegressionWithLBFGS.train()" runs
"treeAggregate at LBFGS.scala:218" but the same command in pyspark with Spark
2.1 runs "treeAggregate at LogisticRegression.scala:1092". This non-optimized
version is much slower and produces a different answer from LBFGS.
