Hive Metastore ERD

In an effort to understand the underpinnings of Hive and HCat, I started reverse engineering the metastore ERD from MySQL and figured others might find this handy. While the API-only crowd might find this verboten, I find its an easy way to understand quickly how useful Hive/Hcat is beyond just writing HQL (see my blog HCatalog - Embrace the independence).

    Virtual data room has an in-built file encryption system that prevents data getting leaked while being transferred. Besides all this, the VDR will even scan your files and documents for viruses.
