  • A Java IDE like Eclipse or IntelliJ

Lab environment:

A working HBase cluster will be provided for students. Students would need an SSH client and a browser to access the cluster.

Zero Install : There is no need to install HBase software on students’ machines!

Überblick

In diesem Kurs wird HBase vorgestellt - ein No SQL Speicher über Hadoop . Der Kurs richtet sich an Entwickler, die HBase zum Entwickeln von Anwendungen verwenden, sowie an Administratoren, die HBase-Cluster verwalten.

Wir werden einen Entwickler durch die HBase-Architektur sowie die Datenmodellierung und Anwendungsentwicklung auf HBase führen. Außerdem werden die Verwendung von MapReduce mit HBase und einige Verwaltungsthemen im Zusammenhang mit der Leistungsoptimierung erläutert. Der Kurs ist sehr praktisch mit vielen Laborübungen.


Dauer : 3 Tage

Zielgruppe : Entwickler und Administratoren
