L1 regularized Logistic regression ?

does mllib support this?

I do see Lasso impl here
https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/mllib/regression/Lasso.scala

if it supports LR , could you please show me a link? what algorithm does it
use?

thanks

I haven't run this, but there is an elasticnetparam for Logistic Regression
here:
https://spark.apache.org/docs/2.0.2/ml-classification-regression.html#logistic-regression


You'd set elasticnetparam = 1 for Lasso
