Without a proper metadata management – it is like you buying a million dollar home with no power connection. There is not much you can do with it!
Metadata management is still a problem in the traditional data management landscape and now with the Big Data and technologies like Hadoop – it is becoming even more complex. The whole value of Hadoop is the freedom it provides. It doesn’t enforce to get fit into a schema. You are no more just restricted to structured data and so on.
