MaxCompute allows you to create external data sources and use the external data sources to connect to Hadoop clusters. After the connection is established, you can implement the lakehouse solution. This topic describes how to create, view, and delete an external Hadoop data source.
Background information
You can map external Hadoop data sources to external MaxCompute projects. The mappings
help you use MaxCompute to query data from one external Hadoop data source or multiple
external Hadoop data sources at a time. MaxCompute allows you to create, view, and
delete external Hadoop data sources. For more information, see the following topics:
Usage notes
- You can create external data sources for MaxCompute in the following regions: China (Hangzhou), China (Shanghai), China (Beijing), China (Shenzhen), China (Zhangjiakou), and Singapore (Singapore).
- You can bind one external data source to only one external MaxCompute project.
- You can create, view, and delete external data sources, but you cannot update the external data sources.
