Apache Flume – Environment
We already discussed the architecture of Flume in the previous chapter. In this chapter, let us see how to download and setup Apache Flume. Before proceeding further, you need to…
Apache Flume – Data Flow
Flume is a framework which is used to move log data into HDFS. Generally events and log data are generated by the log servers and these servers have Flume agents…
Apache Flume – Architecture
The following illustration depicts the basic architecture of Flume. As shown in the illustration, data generators (such as Facebook, Twitter) generate data which gets collected by individual Flume agents running on them. Thereafter, a data…
Apache Flume – Data Transfer In Hadoop
Big Data, as we know, is a collection of large datasets that cannot be processed using traditional computing techniques. Big Data, when analyzed, gives valuable results. Hadoop is an open-source framework that allows…
Apache Flume Tutorial
Flume is a standard, simple, robust, flexible, and extensible tool for data ingestion from various data producers (webservers) into Hadoop. In this tutorial, we will be using simple and illustrative…
SciPy – CSGraph
CSGraph stands for Compressed Sparse Graph, which focuses on Fast graph algorithms based on sparse matrix representations. Graph Representations To begin with, let us understand what a sparse graph is and…
SciPy – Stats
All of the statistics functions are located in the sub-package scipy.stats and a fairly complete listing of these functions can be obtained using info(stats) function. A list of random variables available can also be…
SciPy – Optimize
The scipy.optimize package provides several commonly used optimization algorithms. This module contains the following aspects − Unconstrained and constrained minimization of multivariate scalar functions (minimize()) using a variety of algorithms (e.g. BFGS,…
SciPy – Ndimage
The SciPy ndimage submodule is dedicated to image processing. Here, ndimage means an n-dimensional image. Some of the most common tasks in image processing are as follows &miuns; Input/Output, displaying…
SciPy – Linalg
SciPy is built using the optimized ATLAS LAPACK and BLAS libraries. It has very fast linear algebra capabilities. All of these linear algebra routines expect an object that can be converted into a two-dimensional…
