Code formation

hadoopadm1

Durée

21 heures (généralement 3 jours pauses comprises)

Pré requis

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

Aperçu

Apache Hadoop est le framework le plus répandu pour le traitement de Big Data sur des clusters de serveurs. Dans ce cours de trois (facultatif, quatre jours), les participants découvriront les avantages commerciaux et les cas d'utilisation de Hadoop et de son écosystème, comment planifier le déploiement et la croissance d'un cluster, comment installer, gérer, surveiller, dépanner et optimiser Hadoop . Ils s'exerceront également au chargement en bloc de données en grappe, se familiariseront avec les différentes distributions Hadoop et s'exerceront à installer et à gérer les outils écosystémiques Hadoop . Le cours se termine par une discussion sur la sécurisation d'un cluster avec Kerberos.

“… Les matériaux étaient très bien préparés et couverts à fond. Le laboratoire était très serviable et bien organisé ”
