"Hopefully this has illustrated some points about using and abusing tools like Hadoop for data processing tasks that can better be accomplished on a single machine with simple shell commands and tools. If you have a huge amount of data or really need distributed processing, then tools like Hadoop may be required, but more often than not these days I see Hadoop used where a traditional relational database or other solutions would be far better in terms of performance, cost of implementation, and ongoing maintenance."
