In this case, the entire sentence will be split into 5 tokens one for each word with a value 1 as shown below —. After the map phase execution is completed successfully, shuffle phase is executed automatically wherein the key-value pairs generated in the map phase are taken as input and then sorted in alphabetical order. After the shuffle phase is executed from the WordCount example code, the output will look like this -. In the reduce phase, all the keys are grouped together and the values for similar keys are added up to find the occurrences for a particular word.
It is like an aggregation phase for the keys generated by the map phase. The reducer phase takes the output of shuffle phase as input and then reduces the key-value pairs to unique keys with values added up. In Spark, a DataFrame is a distributed collection of data organized into named columns. In this example, we read a table stored in a database and calculate the number of people for every age. A simple MySQL table "people" is used in the example and this table has two columns, "name" and "age".
