Course Description

What is the difference between Hadoop developer and administrator? A developer can take over the job of a Hadoop administrator whereas an admin can't play the role of a developer unless he has adequate programming knowledge. However, with the huge and complex production environment, now companies need dedicated Hadoop administrators.DBA Responsibilities Performed by a Hadoop Administrator: Data modelling, design & implementation based on recognized standards. Software installation and configuration. Database backup and recovery. Database connectivity and security. Performance monitoring and tuning.Does Hadoop require coding? Although Hadoop is a Java-encoded open-source software framework for distributed storage and processing of large amounts of data, Hadoop does not require much coding. ... All you have to do is enroll in a Hadoop certification course and learn Pig and Hive, both of which require only the basic understanding of SQL Disk space management.
