# hadoop vs eureka

hadoop and eureka share 3 technologies: JAX-RS, com.google.inject:guice, and xercesImpl. Both are written in Java.

- [apache/hadoop](https://seerepo.com/r/apache/hadoop): Apache Hadoop
- [Netflix/eureka](https://seerepo.com/r/Netflix/eureka): AWS Service registry for resilient mid-tier load balancing and failover.

- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
