To access your data in Apache Impala, create a connection asset for it.
Apache Impala provides high-performance, low-latency SQL queries on data that is stored in popular Apache Hadoop file formats.
Supported versions
Apache Impala 1.3+
Create a connection to Apache Impala
To create the connection asset, you need these connection details:
- Database (optional): If you do not enter a database name, you must enter the catalog name, schema name, and the table name in the properties for SQL queries.
- Hostname or IP address
- Port number
- Username and password
- SSL certificate (if required by the database server)
Choose the method for creating a connection based on where you are in the platform
- In a project
- Click Assets > New asset > Connect to a data source. See Adding a connection to a project.
- In a deployment space
- Click Import assets > Data access > Connection. See Adding data assets to a deployment space.
- In the Platform assets catalog
- Click New connection. See Adding platform connections.
Next step: Add data assets from the connection
Where you can use this connection
You can use Apache Impala connections in the following workspaces and tools:
Projects
- Data Refinery
- SPSS Modeler
- Synthetic Data Generator
Catalogs
- Platform assets catalog

Restriction
