This lab describes how to run Hadoop jobs on Alibaba Cloud E-MapReduce. E-MapReduce is a systematic solution for big data processing. It runs on Alibaba Cloud Elastic Compute Service (ECS) based on open-source Apache Hadoop and Apache Spark. You can analyze and process your data by using peripheral systems (such as Apache Hive, Apache Pig, and HBase) in the Hadoop and Spark ecosystems.
