Data Domain Discovery on Hadoop

Data Domain Discovery on Hadoop

Data domain discovery is the process of discovering column names or column data in the data sources that match predefined formats. You can run a data domain profile on Hadoop and view the results.
Data domain discovery results display statistics about columns that match data domains, including the percentage of matching column data and whether column names match data domains. You can drill down the results further for analysis, verify the results on all the rows of the data source, and add the results to a data model.
