Data Lake Compute allows you to configure an EMR Hive data source for multi-source federated data analysis.
Relevant permissions are required for you to select the EMR Hive instance.
The IP range of the selected data engine cannot be the same as that of the EMR instance; otherwise, a network conflict will occur, and you cannot query or analyze data.
After the data catalog is created, you can switch to it from the Data catalog menu on the Data Explore page.
At this point, you can query and analyze the data catalog with SQL statements.
Select the data engine bound when the data catalog is created and click Run to get the query result.
You can only query the data catalog with its bound data engine. To change the bound engine, click the set icon next to the data catalog.
