What is the reason Hadoop Stack is in demand, aside from unstructured data, log processing or one big fat table in append or overwrite table mode?

Forget abt general niche solution Simple Historical Data Loading with Update is not possible though with Hive 14 ACID is started but at least 2--3 years it will take .

Forget abt general niche solution Simple Historical Data Loading with Update is not possible though with Hive 14 ACID is started but at least 2–3 years it will take . Currently of all the hypes the process is drop org table , merge with delta with some non performant sql with unions and then re-create the table . Then there is that serial surrogate key generator . so if i have say 100 TB database and just to load say 50–60 GB delta i will have to drop at least 30–40 Tb and re-create it again ( Leaving aside the Fact tables ) . Also what abt data correction ad hoc . With index and partition also it is heavy duty . for datat mining also any day any time still and near future traditional dbs will beat hadoop stack in performance as well as functionality .
