For more information, see Date Functions.įor more information about Hive data types, see Dates (Link opens in a new window) on the Apache Hive website. Use DATEPARSE() when working with an extract, otherwise use DATE(). You can create a calculated field that uses the DATEPARSE or DATE function to convert a string to a date/time format. However, if you store date/time data as a string in Hive, be sure to store it in ISO format (YYYY-MM-DD). Tableau supports TIMESTAMP and DATE types natively. Work with Hadoop Hive data Work with date/time data To update the list of Search Domains, go to System Preferences > Network > Advanced, and then open the DNS tab. If you use Tableau Desktop on a Mac, when you enter the server name to connect, use a fully qualified domain name, such as, instead of a relative domain name, such as mydb or mydb.test.Īlternatively, you can add the domain to the list of Search Domains for the Mac computer so that when you connect, you need to provide only the server name. Note: This database type only support equal (=) join operations. For more information, see Connect to a Custom SQL Query. Use custom SQL to connect to a specific query rather than the entire data source. In the Table text box, select the search icon or enter the table name and select the search icon, and then select the table.ĭrag the table to the canvas, and then select the sheet tab to start your analysis. For example, use a data source naming convention that helps other users of the data source figure out which data source to connect to.įrom the Schema drop-down list, select the search icon or enter the schema name in the text box and select the search icon, and then select the schema. (Optional) Select the default data source name at the top of the page, and then enter a unique data source name for use in Tableau. On the data source page, do the following: If you still can't connect, yourĬomputer is having trouble locating the server. If Tableau can't make the connection, verify that your credentials are correct. Select the Require SSL option when connecting to an SSL server. For more information, see Run Initial SQL. (Optional) Select Initial SQL to specify a SQL command to run at the beginning of every connection, such as when you open the workbook, refresh an extract, sign in to Tableau Server, or publish to Tableau Server. In the Authentication drop-down list, select the authentication method to use.Įnter the information that you are prompted to provide. The information you are prompted for depends on the authentication method you choose. Then do the following:Įnter the name of server that hosts the database. For a complete list of data connections, select More under To a Server. Start Tableau and under Connect, select Hortonworks Hadoop Hive. Make the connection and set up the data source To get the latest drivers, see Hortonworks Hadoop Hive (Link opens in a new window) on the Tableau Driver Download page. Note: Make sure you use the latest available drivers. If the driver is not installed on your computer, Tableau displays a message in the connection dialog box with a link to the Driver Download (Link opens in a new window) page where you can find driver links and installation instructions. You might already have the required driver installed on your computer. This connector requires a driver to talk to the database. (Optional) Initial SQL statement to run every time Tableau connects Sign-in credentials depend on the authentication method you choose and can include the following: Transport options depend on the authentication method you choose and can include the following: Microsoft Azure HDInsight Service (starting in version 10.2.1) Name of the server that hosts the database you want to connect to Before you beginīefore you begin, gather this connection information: This article describes how to connect Tableau to a Hortonworks Hadoop Hive database and set up the data source.
