I have three months to prepare for this course. What books/resources would you recommend? There is no course textbook.

Course Description:
This course prepares you to process large data sets efficiently. You will be introduced to nonrelational databases and algorithms that allow for the distributed processing of large data sets across clusters.
Competencies
Implement algorithms that allow for the distributed processing of large data sets across computing clusters. Create parallel algorithms that can process large data sets. Use tools and software such as Hadoop, Pig, Hive, and Python to compare large data-processing tasks using cloud-computing services.
