MapReduce serves two essential functions: it filters and parcels out work to various nodes within the cluster or map, a function sometimes referred to as the mapper, and it organizes and reduces the results from each node into a cohesive answer to a query, referred to as the reducer. read less

No Learning Hadoop is not very difficult. Hadoop is a framework of java. Java is not a compulsory prerequisite for learning hadoop. Hadoop has additional abstract framework like Pig and Hive which does not use Java except when there is a need to write user defined functions

Hi, What is opinion on Big data analytics for MBA graduates who doesn't know coding. Please suggest. Is it Coding related course.
You should focus on the analytics part of Data Science, and not on big data. Analytics require knowledge of business along with Data Science skills.

Hi, I have been working in IT from the past six years. My primary skills are Unix and SQL. Can I go for a Spark or Hadoop training? Do I need to learn Python for big data? Is there any skill I need to have for spark?
Python is not mandatory for learning spark. But if you have some core Java skills, that will be the add on to learn spark.
