Drill Explorer Introduction
Drill Explorer is a user interface for browsing Drill data sources, previewing the results of a SQL query, and creating a view. Typically, you use Drill Explorer to explore data or to create a view that you can query as if it were a table. For example, before designing a report using a BI reporting tool, use Drill Explorer to quickly familiarize yourself with the data. In an ODBC-compliant BI tool, use the ODBC DSN to create an ODBC connection.
You can connect Drill to a Hive data source, use Drill Explorer to create a view, and connect to the view as if it were a table. Similarly, you can connect Drill to HBase, Parquet, JSON, CSV, or TSV files, create a view, and query the view as if it were a table.
The default schema that you configure in the DSN may or may not carry over to an application’s data source connections. You may need to re-select the schema.
