Portfolio Projects

Description

Description:

The objective of this project is creating Hive External tables from Master tables and preprocessing and storing it back to Hive External tables and further will be used for data scientists to train their models.

Responsibilities:

  • Worked with CDH Cluster containing 64 Nodes Production Cluster and 36 Nodes Development cluster.
  • Responsible for coordinating end to end project related activities.
  • Involved in all phases of the SDLC including development, testing, and deployment of the application in the Hadoop cluster.
  • Understand the business requirement from Data scientists and data will be dumped from hive external table into another hive external table with partition and specific duration from master table.
  • After a successful data load into hive table it will be accessed by pyspark.
  • Developed pyspark script and further loaded into hive tables to train their models.
  • Used Sbt to compile & package the Scala code into jar and deployed the same in cluster using spark-submit
