Big Data - Hadoop

What is Big Data ?

Big data is a term that describes the large volume of data – both structured and unstructured – that inundates a business on a day-to-day basis. Big data is a term used to refer to data sets that are too large or complex for traditional data-processing application software to adequately deal with. Data with many cases (rows) offer greater statistical power, while data with higher complexity (more attributes or columns) may lead to a higher false discovery rate. Big data challenges include capturing data, data storage, data analysis, Search, sharing, transfer, visualization, querying, updating, information privacy and data source. Big data was originally associated with three key concepts: volume, variety, velocity and veracity.

  • Who can learn Big Data?

  • While anyone who is an intelligent technologist, can very easily pick up the skills for Hadoop, there happen to be certain pre-requisites that a candidate must fulfil. While there happens to be no hard and fast rule about knowing certain tricks very well, but it is kind of mandatory for a candidate to at least know the workings of Java and Linux.



  • What do I Learn?

  • Data Structure, Python, Machine Learning using Python and Hadoop, Supervised and unsupervised learning, Scikit and Hadoop, Hadoop Cluster Architecture, Apache Spark, Scala
