In Scala, to create Pair RDDs from a regular RDD, we simply need to return a tuple from our function. Example 4-2. Scala create pair RDD using the first word as the key. input.map(x => (x.split(" ")(0), x)) Java doesn’t have a built-in tuple type, so Spark’s Java API has users create tuples using the scala.Tuple2 class.

We created multiple custom functions to help process the data, including isAllDigits, countSubstring, hasColumn, and similarity functions. Two more help functions have also been used to store the entities into HashMap and sort them by the tf-df score. These custom functions can be found in globalevent.scala in GlobalEvents_Code.zip.
