Developer

• Project involves SLA Based data transfer (Frequency Hourly and Daily) of Yahoo Meta Data from RDMS to Hadoop File System. Design and development of highly configured interface with minimum disk/network IO data transfer tools. Development of library to generate dynamic SQL to extract data from DB. Development of library to generate delta changes of data and merge to complete full data in Map Reduce process in Hadoop to avoid consumer to implement merging logic. Added retention feature configurable per dimension.
• Create Hive external table, load dimension data and develop canned query for customer.

• Automation of Data Quality is the key Area of each Testing in our each project. So we use various Techniques to Develop QE Data. i.e 1) Data Sampling using Production Data. 2) Data Generator 3) Apply functional specification to generate various flavor of input data from production data. Automation of
• DQ Test Techniques use Data Size Check, Check Sum, Spot Check (dynamic Validation), Golden Data Check (static validation).
• Design a backend testing strategy for testing components and new features of the ETL process to move data from various Yahoo properties to Hadoop based warehouses on the grid.
• Design a strategy using Pig and Perl to validate petabytes of unstructured data in Hadoop to ensure release of new features on time with quality data.
• Develop and maintain an automated regression test suite that caught on an average 4 bugs prior t0 each build thus reducing support costs.
• Automation framework for the project in Perl to suit the need of this project.
• Develop the testing strategy for data Validation and data Integrity for Everest, an internally developed distributed database engine built on top of PostgreSQL code base.
