Indentation

Use 2-space indentation in general. For function declarations, use 4 space indentation for its parameters when they don't fit in a single line. For example:

Code Block
scala
scala

// Correct:
if (true) {
  println("Wow!")
}

// Wrong:
if (true) {
    println("Wow!")
}

// Correct:
def newAPIHadoopFile[K, V, F <: NewInputFormat[K, V]](
    path: String,
    fClass: Class[F],
    kClass: Class[K],
    vClass: Class[V],
    conf: Configuration = hadoopConfiguration): RDD[(K, V)] = {
  // function body
}

// Wrong 
def newAPIHadoopFile[K, V, F <: NewInputFormat[K, V]](
  path: String,
  fClass: Class[F],
  kClass: Class[K],
  vClass: Class[V],
  conf: Configuration = hadoopConfiguration): RDD[(K, V)] = {
  // function body
}

Code documentation style

Use Java docs style instead of Scala docs style.
