Connect to HDFS Data in RazorSQL

Connect to HDFS from wizards and query HDFS data from the GUI in the RazorSQL database management tool.

The CData JDBC Driver for HDFS enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to HDFS using wizards in RazorSQL.

Create a JDBC Data Source for HDFS Data

  1. Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
  2. In the Connection Wizard that appears, set the following properties:
    • Driver Location: Set this property to the path to the lib subfolder in the installation directory.
    • Driver Class: Set the driver class to cdata.jdbc.hdfs.HDFSDriver.
    • Username: Enter the username. (This property can also be set in the JDBC URL.)
    • Password: Enter the password. (This property can also be set in the JDBC URL.)
    • JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:hdfs: and is followed by a semicolon-separated list of connection properties.

      In order to authenticate, set the following connection properties:

      • Host: Set this value to the host of your HDFS installation.
      • Port: Set this value to the port of your HDFS installation. Default port: 50070

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the HDFS JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.hdfs.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      A typical JDBC URL is the following:

      jdbc:hdfs:Host=sandbox-hdp.hortonworks.com;Port=50070;Path=/user/root;User=root;

Query HDFS Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
