Getting all files from a directory

[Kinnary]

Hi
I want to be able to get all the files from all directories at a particular location on a virtual cluster. What is the best way to do that. Following that, I also want to be able to view the data in each file in a tabular format or a histogram, such that the UI looks nice. I want to be able to use REST api's to do this.

Any ideas?

Thanks,
Kinnary
