The CData ODBC Driver for ApacheHive can be used
from any platform or development technology that supports ODBC, including Sybase
PowerBuilder. This article shows how to connect to Hive data and execute queries from the Database Painter and controls such as the DataWindow.
Create a Profile for the ODBC Driver for ApacheHive
Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for ApacheHive. In the Database Painter, you can use wizards and the UI to work with Hive data.
- If you have not already done so, create an ODBC DSN for ApacheHive. The DSN contains the connection properties required to connect to Hive data. You can use the Microsoft ODBC Data Source Administrator to create and configure DSNs. This is the last step of installing the driver.
Required connection properties are the following:
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
See the help documentation for a guide to creating a Hive DSN.
- In PowerBuilder, click Tools -> Database Painter.
- In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
- On the Connection tab, enter a name for the profile and select the Hive DSN in the Data Source menu.
- To view and modify a table, right-click a table and then click Edit Data -> Grid.
Using Hive Data with PowerBuilder Controls
You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve Hive data into a DataWindow. You can add the following code to the open method:
SQLCA.DBMS = "ODBC"
SQLCA.DBParm = "ConnectString='DSN=CData Hive Source'"
CONNECT USING SQLCA;
dw_customers.SetTransObject(SQLCA);
dw_customers.Retrieve();
