The Hadoop Pantheon
A quick list of the Hadoop tools from Russell Jurney:
Only a couple of years ago, nearly every Hadoop shop built its own ETL, high-level MapReduce language, scheduler, custom Java MapReduce jobs, and the development team often ran the cluster. Furthermore, many types of data processing were ineffective, inefficient or impossible for Hadoop developers.
A different form, but basically the same list as per the overview of the Hadoop Ecosystem.
