We would like to implement Hadoop on our system to improve its performance.
The process works like this: Hadoop will gather data from MySQL database then process it. The output will then be exported back to MySQL database.
Is this a good implementation? Will this improve our system's overall performance? What are the requirements and has this been done before? A good tutorial would really help.
Thanks
Sqoop is a tool designed to import data from relational databases into Hadoop
