Query Hive Data in MySQL Workbench

Execute MySQL queries against live Hive data from MySQL Workbench.

You can use the SQL Gateway from the ODBC Driver for Hive to query Hive data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and work with live Hive data in MySQL Workbench.

Connect to Hive Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Hive data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Query Hive from MySQL Workbench

The steps below outline connecting to the virtual Hive database created in the SQL Gateway from MySQL Workbench and issuing basic queries to work with live Hive data.

Connect to Hive through the SQL Gateway

  1. In MySQL Workbench, click to add a new MySQL connection.
  2. Name the connection (CData SQL Gateway for Hive).
  3. Set the Hostname, Port, and Username parameters to connect to the SQL Gateway.
  4. Click Store in Vault to set and store the password.
  5. Click Test Connection to ensure the connection is configured properly and click OK.

Query Hive Data

  1. Open the connection you just created (CData SQL Gateway for Hive).
  2. Click File -> New Query Tab.
  3. Write a SQL query to retrieve Hive data, like SELECT * FROM `CData ApacheHive Sys`.Customers;

With access to live Hive data from MySQL Workbench, you can easily query and update Hive, just like you would a MySQL database. Get started now with a free, 30-day trial of the CData ODBC Driver for Hive and the CData SQL Gateway.
