Alibaba Cloud Elastic MapReduce (E-MapReduce) is a system solution for big data processing that runs on the Alibaba Cloud platform. E-MapReduce is built on Alibaba Cloud Elastic Compute Service (ECS) and is based on open-source Apache Hadoop and Apache Spark. It facilitates the use of other peripheral systems (for example, Apache Hive) in the Hadoop and Spark ecosystems to analyze and process data. You can also easily import data to and export data from other cloud data storage systems and database systems, such as Alibaba Cloud OSS and Alibaba Cloud RDS.
