Hadoop Letter Count Project
Budget: $10 – $15 USD
1. Write a MapReduce program to find the frequency of each letter, case insensitive, in any input user-specified files. For example, "The quick brown fox jumps over the lazy dog" as input should generate the following output (letter,count) pairs: (T, 2), (H, 1), (E, 3), etc.
2. Your program also must find the total count of letters, case insensitive, from the input. Generate one extra output pair whose key is the string "total" and whose value is the total count of all letters.
