Use the Test button to verify that the connection works. The password for the cluster login account. The cluster login account name for your HDInsight cluster. Replace CLUSTERNAME with the name of your HDInsight cluster. Jdbc:hive2://:443/default transportMode=http ssl=true httpPath=/hive2. Use the drop-down to select the Hive driver. Use the following values for the Add Alias dialog: Property Then select the + icon to create a connection alias. On the left of the SQuirreL SQL window, select Aliases. Use the Add button to add the all of jar files downloaded earlier. Jdbc:hive2://localhost:443/default transportMode=http ssl=true httpPath=/hive2 In the Add Driver dialog, add the following information: Property From the left of the window, select Drivers.įrom the icons at the top of the Drivers dialog, select the + icon to create a driver. From a command line, change your work directory to the one created in the prior step, and then enter the following command to copy files from an HDInsight cluster: scp. Replace CLUSTERNAME with the HDInsight cluster name. In the following script, replace sshuser with the SSH user account name for the cluster. The following steps assume that you have already installed SQuirreL SQL.Ĭreate a directory to contain certain files to be copied from your cluster. SQuirreL SQL is a JDBC client that can be used to remotely run Hive queries with your HDInsight cluster. For example, the following Java code opens a new connection: DriverManager.getConnection(connectionString,clusterAdmin,clusterPassword) ![]() From JDBC clients such as SQuirreL SQL, enter admin name and password in client settings.įrom a Java application, you must use the name and password when establishing a connection. When establishing the connection, use the HDInsight cluster admin name and password to authenticate. These ports aren't exposed to the outside. You can't connect to HiveServer 2 directly on ports 10001 or 10000. HDInsight is a managed service, which means all connections to the cluster are managed via a secure Gateway. You can only use port 443 to connect to the cluster from some places outside of the Azure virtual network. Host name '' in the connection string is the same as your cluster URL. The following connection string shows the format to use for HDInsight: jdbc:hive2://:443/default transportMode=http ssl=true httpPath=/hive2 The public gateway that the clusters sit behind redirects the traffic to the port that HiveServer2 is actually listening on. JDBC connections to an HDInsight cluster on Azure are made over port 443. The Java Developer Kit (JDK) version 11 or higher.Ensure that service HiveServer2 is running. To create one, see Get started with Azure HDInsight. The information in this document demonstrates how to connect programmatically, and from the SQuirreL SQL client.įor more information on the Hive JDBC Interface, see HiveJDBCInterface. To submit Apache Hive queries to Apache Hadoop in Azure HDInsight. You can change which character sequences should be used as the prefix, suffix and part delimiter in a variable expression in Tools->Tool Properties, in the Variables category under the General tab.Learn how to use the JDBC driver from a Java application. To solve this problem either clear the type part of the variable expression or add the option nobind (see above). A simple example is Oracle that does not accept parameter markers for a table name. However, there may be problems once the final statement is passed to the database for execution if it contains parameter markers in non supported places. Variables in DbVisualizer may be used anywhere in a statement. The variable format supports setting a default value, data type and a few options as in the following example: ![]()
