Presentation Transcript
  • Big data is a sweeping term for the non-conventional techniques and advances expected to accumulate, sort out, process, and assemble experiences from vast datasets.
  • While the issue of working with data that surpasses the registering force or capacity of a solitary PC isn't new, the inescapability, scale, and estimation of this sort of figuring has enormously extended as of late.
  • In this article, we will discuss big data on a key level and characterize normal ideas you may go over while exploring the subject.
  • We will likewise investigate a portion of the procedures and innovations right now being utilized as a part of this space.
what is big data
What is Big Data?
  • Big data means really a big data, it is a collection of large datasets that cannot be processed using traditional computing techniques.
  • Big data is not merely a data, rather it has become a complete subject, which involves various tools, technqiues and frameworks.
  • Big Data Training is learn by Greens Technologys.
  • Data that is unstructured or time sensitive or simply very large cannot be processed by relational database engines.
  • This type of data requires a different processing approach called big data, which uses massive parallelism on readily-available hardware.

Big Data includes huge volume, high velocity, and extensible variety of data. The data in it will be of three types.

  • Structured data : Relational data.
  • Semi Structured data : XML data.
  • Unstructured data : Word, PDF, Text, Media Logs.
  • Hadoop is an Apache open source system written in java that permits conveyed preparing of extensive datasets crosswise over groups of PCs utilizing basic programming models.
  • The Hadoop outline worked application works in a situation that gives dispersed capacity and calculation crosswise over bunches of PCs.
  • It is intended to scale up from single server to a large number of machines, each offering neighborhood calculation and capacity.
  • It runs applications using the MapReduce algorithm, where the data is processed in parallel on different CPU nodes.
hadoop architecture
Hadoop Architecture

Hadoop framework includes following four modules:

  • Hadoop Common: These are Java libraries and utilities required by other Hadoop modules. These libraries provides filesystem and OS level abstractions and contains the necessary Java files and scripts required to start Hadoop.
  • Hadoop YARN: This is a framework for job scheduling and cluster resource management.
  • Hadoop Distributed File System (HDFS™): A distributed file system that provides high-throughput access to application data.
  • Hadoop MapReduce: This is YARN-based system for parallel processing of large data sets.

Hadoop MapReduce is a product system for effortlessly composing applications which process enormous measures of information in-parallel on extensive groups of item equipment in a dependable, blame tolerant way.

The term MapReduce really alludes to the accompanying two unique undertakings that Hadoop programs perform:

  • The Map Task: This is the principal assignment, which takes input information and proselytes it into an arrangement of information, where singular components are separated into tuples (key/esteem sets).
  • The Reduce Task: This undertaking takes the yield from a guide errand as information and joins those information tuples into a littler arrangement of tuples. The lessen errand is constantly performed after the guide undertaking.
  • HDFS holds expansive measure of information and gives less demanding access. To store such immense information, the documents are put away over various machines. These documents are put away in excess design to safeguard the framework from conceivable information misfortunes if there should arise an occurrence of disappointment.

Highlights of HDFS

  • It is reasonable for the conveyed stockpiling and handling.
  • Hadoop furnishes a summon interface to connect with HDFS.
  • The inherent servers of namenode and datanode help clients to effectively check the status of group.
  • Gushing access to document framework information.
  • HDFS gives record consents and validation.
what is impala
What is Impala?
  • Impala is a MPP (Massive Parallel Processing) SQL question motor for handling colossal volumes of information that is put away in Hadoop group.
  • It is an open source programming which is composed in C++ and Java. It gives superior and low idleness contrasted with other SQL motors for Hadoop.
  • As such, Impala is the most elevated performing SQL motor (giving RDBMS-like involvement) which gives the speediest method to get to information that is put away in Hadoop Distributed File System.
  • Impala is available freely as open source under the Apache license.
  • Impala supports in-memory data processing, i.e.,
  • You can access data using Impala using SQL-like queries.
  • It is wide-section store database in light of Apache Hadoop.
  • It utilizes the ideas of Big Table.
  • Its data model is wide column store.
  • It is developed using Java language.
  • The data model of HBase is schema-free.
  • It provides Java, RESTful and, Thrift API’s.
  • Supports programming languages like C, C#, C++, Groovy, Java, PHP, Python and Scala.
  • It provides support for triggers.
