Course Code

hadoopadm1

Duration

21 hours (usually 3 days including breaks)

Requirements

comfortable with basic Linux system administration
basic scripting skills

Knowledge of Hadoop and Distributed Computing is not required, but will be introduced and explained in the course.

Lab environment

Zero Install : There is no need to install hadoop software on students’ machines! A working hadoop cluster will be provided for students.

Students will need the following

an SSH client (Linux and Mac already have ssh clients, for Windows Putty is recommended)
a browser to access the cluster. We recommend Firefox browser with FoxyProxy extension installed

Overview

Apache Hadoop is het populairste framework voor het verwerken van Big Data op clusters van servers. In deze drie (eventueel vier) dagen cursus, zullen de deelnemers leren over de zakelijke voordelen en use cases voor Hadoop en zijn ecosysteem, hoe cluster inzet en groei plannen, hoe te installeren, onderhouden, monitor, problemen oplossen en optimaliseren van Hadoop . Ze zullen ook oefenen met het bulksgewijs laden van gegevens, vertrouwd Hadoop met verschillende Hadoop distributies en oefenen met het installeren en beheren van Hadoop ecosysteemtools. De cursus eindigt met een bespreking van het beveiligen van cluster met Kerberos.

“… De materialen waren zeer goed voorbereid en grondig bedekt. Het lab was erg behulpzaam en goed georganiseerd ”
