MapR Cluster Administration Training
The Training sessions are usually held in German. Please contact us if you are interested in Training sessions in English.
This Training provides the knowledge required to develop Big Data Applications on the basis of Apache Spark 2.1.
Participants first learn how to use the Spark shell to load data sets from various sources and formats and analyse them interactively. Building on that, the participants then develop an independent Spark application to process data in the form of data sets and DataFrames locally or in a computing cluster.
The Training is rounded off with an introduction to Spark Streaming for the processing of data streams, GraphFrame for the analysis of graphs and the machine-learning library MLlib.
Introduction to the MapR Converged Data Platform (HDFS core components, MapR-FS core components, MapR-FS versus HDFS)
