Summary

In this chapter, we started out by exploring the history of Apache Hadoop and moved on to understanding its specific components. We also introduced ourselves to the new version of Apache Hadoop. We learned about Cloudera and its Apache Hadoop distribution called CDH and finally looked at some important roles and responsibilities of an Apache Hadoop administrator.

In the next chapter, we will get a more detailed understanding of Apache Hadoop's distributed filesystem, HDFS, and its programming model, MapReduce.
