Apache Hive connection
To access your data in Apache Hive, create a connection asset for it.
Apache Hive is a data warehouse software project that provides data query and analysis and is built on top of Apache Hadoop.
Supported versions
Apache Hive 1.0.x, 1.1.x, 1.2.x. 2.0.x, 2.1.x, 3.0.x, 3.1.x.
Create a connection to Apache Hive
To create the connection asset, you need the following connection details:
- Database name (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
- HTTP path (optional): The path of the endpoint such as the gateway, default, or hive if the server is configured for the HTTP transport mode.
- Username and password
- If required by the database server, the SSL certificate
For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.
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 catalog
- Click Add to catalog > Connection. See Adding a connection asset to a catalog.
- 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 the Apache Hive connection in the following workspaces and tools:
Projects
- Data quality rules (IBM Knowledge Catalog)
- Data Refinery (Watson Studio or IBM Knowledge Catalog)
- DataStage (DataStage service). For more informartion, see Connecting to a data source in DataStage.
- Decision Optimization (Watson Studio and Watson Machine Learning)
- Metadata enrichment (IBM Knowledge Catalog)
- Metadata import (IBM Knowledge Catalog)
- SPSS Modeler(Watson Studio)
- Watson Machine Learning Accelerator (Watson Machine Learning Accelerator service)
Catalogs
-
Platform assets catalog
-
Other catalogs (IBM Knowledge Catalog)
- Watson Query service
- You can connect to this data source from Watson Query.
Apache Hive setup
Restriction
You can use this connection only for source data. You cannot write to data or export data with this connection.
Running SQL statements
