IMPACT Marketing J2EE + Hadoop DeveloperDescription: IMPACT is a marketing project to maintain customer profile, send promotions, coupons,prices across customers and stores. Customer profile is managed using web application build using J2EE technologies. IMPACT also collects and analysis the collected big data. This is implemented through batch processing which runs on legacy systems or tools like Datastage. The batch runs daily and processes large volumes of data (in terabytes ) which is both cost and time consuming. In IMPACT project we migrating the batch processing of data from Datastage to Hadoop/PIG/Java .We are doing this by running the PIG map-reduce jobs on Hadoop cluster .This helped us not only in reducing the cost as Hadoop/PIG is open source software that can be run on cheap commodity hardware across many different servers. It also helped to quickly analyze massive quantities of information or data in real-time as compared to Datastage .Currently the components or interfaces implemented in Hadoop Pig are processing double the volume of data (in terabytes ) in one fourth of time as compared to conventional processing of data in Datastage.Responsibilities• Migration of Datastage jobs to Hadoop/Pig by developing code in Hadoop/Pig and Java with distributed systems.• Understanding the business requirements and implementing the necessary change or new requests in various Hadoop/Pig interfaces.• Understanding the system and business concepts of data flow across the application .• Performance tuning of Hadoop jobs against very large data files or datasets .• Performing QA and testing of the Hadoop/PIG jobs before final production deployment . • Played a substantial role in defining processes and in gathering business and functional requirements.
