While I am reading CSV data from a directory which contains double values and applying streaming K-means model on it as follows,

//CSV file

40.729,-73.9422
40.7476,-73.9871
40.7424,-74.0044
40.751,-73.9869
40.7406,-73.9902
.....

//SBT dependencies:

name := "Application name"

version := "0.1"

scalaVersion := "2.11.12"
val sparkVersion ="2.3.1"

libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % sparkVersion,
"org.apache.spark" % "spark-streaming_2.11" % sparkVersion,
"org.apache.spark" %% "spark-mllib" % "2.3.1")

//import statement
