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 distrib-
uted filesystem, HDFS, and its programming model, MapReduce.
