Scaling out data preprocessing with Hive

We introduce a user-friendly graphical data preprocessing application based on Hive, one of the well known opensource distributed warehouse systems. It is comfortable, and easy to use for preprocessing purposes, but to prove usability of this application, we created measurement a framework to ensure precise results. These results show that our application has outstanding scaling capability in the case of increasing data amount and increasing number of applied computers. We conclude that this is a good solution for medium and large scale data preprocessing.
