  Command-line Tools can be 235x Faster than your Hadoop Cluster (2014)

  Conclusion: 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.

JQ is very convenient, even if your files are more than 100GB. I often need to extract one field from huge JSON line files, I just pipe jq to it to get results. It's slower, but implementing proper data processing will take more time.

are those tools known for their fast json parsers?
