Suyog Nagaokar is a software engineer and educator focused on the Hadoop / big-data ecosystem — the foundational platform for processing data at scale that anchored a generation of data-engineering work.
His CourseFlix listing carries Data Engineering with Hadoop — a structured treatment of the Hadoop ecosystem: HDFS, MapReduce, YARN, the Hive / Pig / Spark layers on top, and the operational patterns for running Hadoop clusters in production.
Material is paid and aimed at data engineers picking up Hadoop for legacy or current production systems. For broader content, see CourseFlix's Data processing and analysis category page.
