Quick Purchase of a Hadoop Analysis Cluster

Updated at: Dec 31, 2019 GMT+08:00

This section describes how to quickly purchase a Hadoop analysis cluster for analyzing and querying vast amounts of data. In the open source Hadoop ecosystem, Hadoop uses Yarn to manage cluster resources, Hive and Spark to provide offline storage and computing of large-scale distributed data, Spark Streaming and Flink to offer streaming data computing, and Presto to enable interactive queries, Tez to provide a distributed computing framework of directed acyclic graphs (DAGs).
