The order of the columns in a workbook and in a Hive table no longer need to be identical. Also, mapping errors are now clearly marked in a red color (in the UI) for quicker troubleshooting.
Defer Importing Sample Data from a Data Link
For data links, users have the option to generate sample data immediately after saving the data link (this saves the sample data to the DM private folder during the data link ingestion) or deferring sample data generation until using the data link in a workbook. Deferring sample generation is useful for when the data link is available to multiple users but each user may have different access to the original source of the data link. When deferring sample data, the sample data is created and stored in the DM private folder by the workbook user rather than the data link creator. This sample data access still follows impersonation security policies (e.g., Sentry/Ranger).
