Kurskode

hadoopadm1

Varighet

21 timer (vanligvis 3 dag inkludert 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

Oversikt

Apache Hadoop er den mest populære rammen for behandling av Big Data på klynger av servere. I dette tre (eventuelt fire dager) kurset vil deltakerne lære om forretningsfordelene og bruke saker for Hadoop og dets økosystem, hvordan planlegge klyngedistribusjon og vekst, hvordan installere, vedlikeholde, overvåke, feilsøke og optimalisere Hadoop . De vil også øve på datalast av klynge, bli kjent med forskjellige Hadoop distribusjoner og øve på å installere og administrere Hadoop økosystemverktøy. Kurset avsluttes med diskusjon om å sikre klynge med Kerberos.

“… Materialene var veldig godt forberedt og dekket grundig. Laben var veldig hjelpsom og godt organisert ”
