Hadoop is one of many tools a hiring manager may specifically inquire about. Being asked about your experience with a specific tool or language is most likely an indication that it is something used on the job. Prepare for the interview by researching which languages and tools they use at the hiring organization. In most cases, this would be outlined in the job description. If you have little or no experience with the specified tools or languages, conduct research to at least show you have some knowledge of them. If you do have experience with the tool, make sure the explanation of your project reflects your knowledge of its capabilities.

"Yes, I have had experience utilizing the Hadoop framework on a project where my team was tasked with increasing data processing efficiency. The Hadoop framework was implemented to increase data processing speeds without compromising quality through its distributed processing. Hadoop was also chosen for its scalability as our organization anticipated our data processing needs would increase significantly in the near future. This project had limited resources so Hadoop was an attractive choice because it has a open-source framework. It is also Java-based which reduced the training required as most of our team was familiar with the language."
