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

• Amazon Elastic MapReduce 2.1.4+
• Apache Hadoop Hive
• Cloudera CDH3 update 4+
• Hortonworks 1.3+
• MapR 1.2+
• Pivotal HD Enterprise 2.0.1

Create a connection to Apache Hive

To create the connection asset, you need these connection details:

• Database name
• 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
• SSL certificate (if required by the database server)

For Credentials and Certificates, you can use secrets if a vault is configured for the platform and the service supports vaults. For information, see Using secrets from vaults in connections.

Choose the method for creating a connection based on where you are in the platform

In a project Click Add to project > Connection. 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 Add to space > Connection. See Adding connections to a deployment space.

In the Platform assets catalog Click New connection. See Adding platform connections.

Next step: Add data assets from the connection

• See Add data from a connection in a project.
• See Add data from a connection in a catalog.

Where you can use this connection

You can use the Apache Hive connection in the following workspaces and tools:

Analytics projects

• Data Refinery (Watson Studio or Watson Knowledge Catalog)
• DataStage (DataStage service)
• Metadata import (Watson Knowledge Catalog)
• Notebooks (Watson Studio). Use the insert-to-code function to get the connection credentials and load the data into a data structure. See Load data from data source connections.
• SPSS Modeler (SPSS Modeler service)

Catalogs

• Platform assets catalog
• Other catalogs (Watson Knowledge Catalog)

Data Virtualization service You can connect to this data source from Data Virtualization.

Apache Hive installation and configuration

Restrictions

• For Data Refinery, you can use this connection only as a source. You cannot use this connection as a target connection or as a target connected data asset.
• For SPSS Modeler, you can use this connection only to import data. You cannot export data to this connection or to an Apache Hive connected data asset.
