Data Source Configuration through a GUI

On Windows, data sources are stored in the Windows Registry. You can configure and modify data sources through the ODBC Administrator using a driver Setup dialog box, as described in this section.
When the driver is first installed, the values of its connection options are set by default. These values appear on the driver Setup dialog box tabs when you create a new data source. You can change these default values by modifying the data source. In the following procedure, the description of each tab is followed by a table that lists the connection options for that tab and their initial default values. This table links you to a complete description of the options and their connection string attribute equivalents. The connection string attributes are used to override the default values of the data source if you want to change these values at connection time.
To configure a Hive data source:
1. Start the ODBC Administrator by selecting its icon from the Progress DataDirect for ODBC program group.
2. Select a tab:
*User DSN: If you are configuring an existing user data source, select the data source name and click Configure to display the driver Setup dialog box.
If you are configuring a new user data source, click Add to display a list of installed drivers. Select the driver and click Finish to display the driver Setup dialog box.
*System DSN: If you are configuring an existing system data source, select the data source name and click Configure to display the driver Setup dialog box.
If you are configuring a new system data source, click Add to display a list of installed drivers. Select the driver and click Finish to display the driver Setup dialog box.
*File DSN: If you are configuring an existing file data source, select the data source file and click Configure to display the driver Setup dialog box.
If you are configuring a new file data source, click Add to display a list of installed drivers; then, select a driver. Click Advanced if you want to specify attributes; otherwise, click Next to proceed. Specify a name for the data source and click Next. Verify the data source information; then, click Finish to display the driver Setup dialog box.
3. The General tab of the Setup dialog box appears by default.
Figure 1. General tab
The General tab of the ODBC Apache Hive Wire Protocol Driver Setup dialog box
On this tab, provide values for the options in the following table; then, click Apply. The table provides links to descriptions of the connection options. The General tab displays fields that are required for creating a data source. The fields on all other tabs are optional, unless noted otherwise.
Connection Options: General
Description
Specifies the name of a data source in your Windows Registry or odbc.ini file.
Default: None
Specifies an optional long description of a data source. This description is not used as a runtime connection attribute, but does appear in the ODBC.INI section of the Registry and in the odbc.ini file.
Default: None
Determines whether the driver uses Apache ZooKeeper when connecting to a database server.
If disabled, the driver does not use ZooKeeper when connecting to a database server. By default, the driver's behavior is determined by the connection options settings.
If enabled, the driver attempts to connect to the member servers of a ZooKeeper ensemble that are specified by the Host Name connection option. At connection, the driver retrieves configuration information from the ZooKeeper service that determines the behavior of the driver for the connection. The retrieved configuration information takes precedent over any values specified using connection options.
Default: Disabled
Specifies the name of the Apache ZooKeeper name space to which you want to retrieve configuration information.
Default: /hiveserver2
The name or the IP address of the server to which you want to connect.
When Apache ZooKeeper support is enabled (ZooKeeperDiscovery=1), this option specifies a comma-seperated list of member servers of the ZooKeeper ensemble to which you want to connect. For example:
server1:10000,255.125.1.11:2818,server3:2828
Default: None
Specifies the port number of the server listener.
Default: 10000
Specifies the name of the Hive database. The database must exist, or the connection attempt will fail.
Default: default
Specifies whether binary (TCP) mode or HTTP mode is used to access Apache Hive data sources.
If set to 0 - binary, Thrift RPC requests are sent directly to data sources using a binary connection (TCP mode).
If set to 1 - HTTP, Thrift RPC requests are sent using HTTP transport (HTTP mode). HTTP mode is typically used when connecting to a proxy server, such as a gateway, for improved security, or a load balancer.
Default: 0 - binary
Specifies the path of the HTTP/HTTPS endpoint used for connections when HTTP mode is enabled (TransportMode=1).
Default: cliservice
Determines whether the driver attempts to use session cookie based authentication for requests to an HTTP endpoint after the initial authentication to the server. Cookie based authentication improves response time by eliminating the need to re-authenticate with the server for each request.
If disabled, the driver does not use cookie based authentication for HTTP requests after the initial authentication.
If enabled, the driver attempts to use cookie based authentication for requests to an HTTP endpoint after the initial authentication to the server. The cookie used for authentication is specified by the Cookie Name option.
Default: Enabled
Specifies the name of the cookie used for authenticating HTTP requests when HTTP mode (TransportMode=1) and cookie based authentication are enabled (EnableCookieAuthentication=1).
Default: If no value is specified, the driver attempts to use the following cookie names by default:
*hive.server2.auth (Hive connections)
*hadoop.auth (Apache Knox connections)
*JSESSIONID (Apache Knox connections)
4. At any point during the configuration process, you can click Test Connect to attempt to connect to the data source using the connection options specified in the driver Setup dialog box. A logon dialog box appears (see "Using a Logon Dialog Box" for details). Note that the information you enter in the logon dialog box during a test connect is not saved.
5. To further configure your driver, click on the following tabs. The corresponding sections provide details on the fields specific to each configuration tab:
*Advanced tab allows you to configure advanced behavior.
*Security tab allows you to specify security data source settings.
6. Click OK. When you click OK, the values you have specified become the defaults when you connect to the data source. You can change these defaults by using this procedure to reconfigure your data source. You can override these defaults by connecting to the data source using a connection string with alternate values.
* Advanced Tab
* Security Tab
