After creating a connection to an ADLS Databricks cluster via Hive, you can create a profiling analysis on a specific file.

Before you begin

Procedure

  1. In the DQ Repository tree view, expand Metadata > DB Connections > the JDBC connection > Tables.
  2. In the Columns folder, select the columns you want to analyze and right-click them.
    Tip: To create an analysis on all columns, right-click the table name.
  3. Hover over Column Analysis and select the analysis type you need.
    The Create New Analysis wizard is displayed.
  4. Enter a name and click Finish. The other fields are optional.
    A new analysis on the selected ADLS files is automatically created and opened in the analysis editor. Depending on the analysis type you have selected, the indicators are automatically assigned for columns.

    The analysis applies to the Hive table, but computes statistics on the data from the ADLS by using the External table mechanism. External tables keep data in the original file outside of Hive. If the ADLS file you selected to analyze is deleted, the analysis will not be able to run anymore.

  5. If needed:
    • Click Select Columns to modify the columns to be analyzed.
    • Click Select Indicators to add more indicators or new patterns to the columns.
  6. Run the analysis to display the results in the Analysis Results view in the editor.

What to do next

You can create a report on this analysis. See Creating a report on specific analyses.
