object apache is not a member of package org

buld.sbt에 아래와 같이 추가

libraryDependencies += "org.apache.spark"% "spark-core_2.10"% "1.6.3" 

아니면 예를 들어 아래와 같이 워닝이 뜨면 디펜던시를 추가해주면 됨

* com.google.code.findbugs:jsr305:1.3.9 is selected over 2.0.1 

* com.google.guava:guava:14.0.1 is selected over 11.0.2

* commons-net:commons-net:2.2 is selected over 3.1

libraryDependencies ++= Seq(

         "org.apache.spark" %% "spark-core" % sparkVersion,

         "com.google.guava" % "guava" % "11.0.2",

         "commons-net" % "commons-net" % "2.2",

         "com.google.code.findbugs" % "jsr305" % "1.3.9"

)

sbt update로 잘되는지 확인..
