Exercise: Word Count Per Record

Write a new Kafka application WordCountPerLineApp (using Kafka Producer and Consumer APIs) that does the following:

1. Consume records from a topic, e.g. input .
2. Count words (in the value of a record).
3. Produce records with the unique words and their occurrences (counts).
   1. A record key -> hello hello world gives a record with the following value hello -> 2, world -> 1 (and the same key as in the input record).

(EXTRA)

4. Produces as many records as there are unique words in the input record with their occurrences (counts)
   1. A record key -> hello hello world gives two records in the output, i.e. (hello, 2) and (world, 1 (as (key, value))
