The document discusses different options for performing data analysis on Hadoop clusters, including Scalding, Scoobi, and Scrunch. It provides a brief overview of each option and code examples. While the options are similar, the author notes they are working to develop a common API. The key takeaways are that functional programming is well-suited for mapreduce problems and using Scalding, Scoobi, or Scrunch can increase productivity over traditional mapreduce.
