Connect to Hive Data in IntelliJ

Integrate connectivity to Hive data with wizards in IntelliJ.

The CData JDBC Driver for Hive enables you to access Hive as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to Hive data in IntelliJ.

Create a JBDC Data Source for Hive

Follow the steps below to add the driver JAR and define connection properties required to connect to Hive data.

  1. In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.
  2. In the Data Source Properties dialog that appears, the following properties are required:

    • JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.apachehive.jar, located in the installation directory.
    • JDBC Driver Class: In this menu, select cdata.jdbc.apachehive.ApacheHiveDriver from the list.
    • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:apachehive: and includes connection properties separated with semicolons.

      Apache Hive への接続を確立するには以下を指定します。

      • Server:HiveServer2 をホストするサーバーのホスト名またはIP アドレスに設定。
      • Port:HiveServer2 インスタンスへの接続用のポートに設定。
      • TransportMode:Hive サーバーとの通信に使用するトランスポートモード。有効な入力値は、BINARY およびHTTP です。デフォルトではBINARY が選択されます。
      • AuthScheme:使用される認証スキーム。有効な入力値はPLAIN、LDAP、NOSASL、およびKERBEROS です。デフォルトではPLAIN が選択されます。
      • 本製品においてTLS/SSL を有効化するには、UseSSL をTrue に設定します

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Hive JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.apachehive.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      A typical JDBC URL is the following:

      jdbc:apachehive:Server=127.0.0.1;Port=10000;TransportMode=BINARY;

Edit and Save Hive Data

To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor. You can also modify records in the Table Editor.
