No, it is not going to replace databases. In one form or other we will be using SQL databases to store and process Big Data.
Detailed explanation-2: -Reasons of RDBMS Failure to handle Big Data Guarantee of ACID properties is a myth. Not possible to stick to normalization. Automatic Sharding of data is almost impossible (nightmare). Very hard to achieve High Availability.
