PROFESSIONAL EXPERIENCE

Confidential, Woburn, MA

Hadoop Developer

Responsibilities:

• Worked onHadoopcluster which ranged from 4-8 nodes during pre-production stage and it was sometimes extended up to 20nodes during production
• Installed and configured HadoopMapreduce, HDFS, Developed multiple MapReduce jobs in java for data cleaning and preprocessing.
• Established custom MapReduce programs in order to analyze data and usedPig Latinto clean unwanted data
• Did various performance optimizations like using distributed cache for small datasets, Partition, Bucketing in hive and Map Side joins.
• Built reusableHiveUDF libraries.
• UsedSqoopto import the data from RDBMS toHadoopDistributed File System (HDFS) and later analyzed the imported data usingHadoopComponents.
• CreatedHive tables, then appliedHiveQLon those tables, this will invoke and run MapReduce jobs automatically
• Performedloading and transforming large sets of Structured, Semi-Structured and Unstructured data and analyzed them by running Hive queries and Pig scripts
• InstalledOozie workflowengine to run multiple Hive and Pig jobs which run independently with time and data availability
• Performed Hadoopinstallation,updates, patches and version upgrades when required
• Bug fixing and 24x7production support
