Big Data - Hadoop Ecosystem, Map-Reduce & HDFS

מק"ט: #3572 | משך קורס: 40 שעות אק'

Hadoop HDFS allows you to manage distributed file system and by that to better use your elastic domains. Hadoop is also, in most cases, is the infrastructure for all the upper level distributed abstractors and services like No-SQL implementations.

This course is designed to introduce you to:

  • Basic no-sql database types, concepts and applications.
  • Hadoop architecture and frameworks.
  • Hadoop eco-system.

Hand on exercises are included.
