Hadoop provides a redundant storage of massive data and computation platform using commodity and potentially unreliable hardware. The cloud/NoSQL track starts with the basics of Hadoop and finishes by comparing two data anlysis projects from the Hadoop ecosystem. #Hadoop Fundamentals: HDFS, MapReduce, Pig, and Hive (Tom White) Unfortunately, a scheduled half hour does not allow any time for detailed and in depth presentation of Mahout. Isabel gives a general introduction into the steps and challenges of machine learning, how the basic algorithms work and how Mahout employes hadoop to deal with large data sets. Typical use cases include pattern mining and data classification, such as for mail classification, news topic discovery or recommendation systems. Mahout is a framework for machine learning, implementing different algorithms for data mining applications. Intelligent data analysis - Apache Mahout (Isabel Drost) Portfolio and this shouldn’t be that hard. Jaroslav managed to get the plugin running, which visualized the CPUįrequency of a local linux box.
