QA Analyst

Confidential

Responsibilities:

• Analyzed requirements thoroughly, identified gaps and suggested to the clients before requirements sign-off.
• Prepared Test Plan, Test cases, Test data and Test Results to ensure the actual results meet end clients need.
• Worked closely with business team and other teams to understand business requirements and successful implementation.
• Involved in Software Development Life Cycle of the project from requirements gathering to deployment in production.
• Compared the sourced data to pushed data to ensure correct data is extracted and loaded into the HDFC location
• Loading and transforming structured and semi structured data in to HDFS successfully using Flume engines.
• Tested and validated the data at all stages of the ETL process using Flume.
• Verified business logic on every single node and then by running multiple nodes for data aggregation and segregation rules.
• Performed output validation for transformation rules, data integrity and successful data load into the target system.
• Involved in performance testing for data storage, timeout, commit logs, message queues.
• Developed medium to complex HiveQL queries for validation, involving joining multiple tables.

Java/Hadoop Developer

Confidential

Responsibilities:

• Understanding the user requirement coming either from the BAs or other stakeholders and driving it from brainstorming to implementation.
• To remove old documents (expired irrelevant data) from MongoDB implemented TTL index and written java class using Spring Task Execution and Scheduling for the case where TTL index cannot be implemented.
• Implementation of feeds using hadoop ecosystem which comprises of capturing user activity on the apps and sending it to business units for analysis and thus giving better user experience.
• Developed end-to-end process to load feed data into mongoDB using HDFS, pig and Oozie workflow. Third party puts “|” delimited feed file into our ingest server using FTP, a scheduled monitoring task polls ingest server at every 5 mins and ingested file gets moved onto HDFS using Hadoop java API and finally Oozie workflow gets triggered using Oozie Client which will run pig script. The pig script loads the feed file and stores relevant data into MongoDB.
• Learned concepts like YARN, HDFS Federation and High Availability introduced in Hadoop 2.X.
• Involved in addressing issues related to slowStart, CPU resource utilization in YARN, Capacity vs Fair scheduling and speculative task execution during Hadoop upgrade from Cloudera CDH 3 (Hadoop 0.20.2) to CDH 4 (Hadoop 2.0).
• Bug fixing and maintenance of existing code for older versions of the apps running on Web platforms.
