Summary

With every Data Lake initiative, over 50 percent of the project time is spent in transforming the data from its raw format to something that can be consumed by the decision makers. In this chapter, we looked at the key tools available for data transformation; Hive and Pig both provide a layer of abstraction over MapReduce and are easy for business users to adopt.
