Summary
This chapter covered many of the additional tools you can use with Hadoop. We gave
special attention to Hive, a data warehousing package that allows you to process data
in Hadoop using an SQL-like language. A rich ecosystem of supporting software has
sprung up around Hadoop, and you'll see some of them in action in the case studies
in the next chapter.
