Apache Hadoop? From my understanding of Apache Hadoop, they're completely different areas. Lapis is a framework for web applications (think Rails, Sinatra, Flask, Revel, Zend, etc.) You write the web applications in Moonscript (which compiles to Lua, if you didn't already know...) to be run on OpenResty (which is Nginx + Lua.) Hadoop, on the other hand, is a set of projects dealing with high performance, distribution, and high availability. To quote their site: > a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures.
So, web frameworks aren't going to help with any of these. That being said, it should be possible to use things like Lapis to communicate with some Hadoop projects, such as ZooKeeper, Cassandra™, Spark™, etc, with the assumption they have some form of network communication for clients (which I'm basically certain they do.) However, the libraries to talk to said services may or may not exist yet.
