hadoopadm1

Varaktighet

21 timmar (vanligtvis 3 dag inklusive pauser)

Krav

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

Översikt

Apache Hadoop är den mest populära ramen för behandling av Big Data på kluster av servrar. I den här tre (valfritt, fyra) dagars kurs kommer deltagarna att lära sig om affärsfördelarna och använda fall för Hadoop och dess ekosystem, hur man planerar distribution och tillväxt av kluster, hur man installerar, underhåller, övervakar, felsöker och optimerar Hadoop . De kommer också att öva kluster bulk data belastning, bekanta sig med olika Hadoop distributioner och öva på att installera och hantera Hadoop ekosystemverktyg. Kursen avslutas med diskussion om att säkra kluster med Kerberos.

”... Materialen var mycket väl förberedda och täckta noggrant. Laben var mycket hjälpsam och välorganiserad ”
