Data Preview for Tables in External Sources
Effective in version 10.1.1, you can preview sample data for external (outside Hadoop data lake) tables if these sources are cataloged. The administrator needs to configure JDBC connections with Sqoop and provide the analysts with requisite permissions. The analyst can connect to the data source using these connections to view the data from assets that are not in the data lake.
For more information, see the "Discover Data" chapter in the
10.1.1 Intelligent Data Lake User Guide.
