Include or exclude classes or packages for a Hadoop configuration

You have the option to include or exclude classes or packages from loading with a Hadoop configuration.

Configure these options within the plugin.properties file located at plugins/pentaho-big-data-plugin. For additional information, see the comments within the plugin.properties file.

• Include Additional Class Paths or Libraries

  To include additional class paths, native libraries, or a user-friendly configuration name, include the directory within classpath property within the big data plugin.properties file.

• Exclude Classes or Packages

  To exclude classes or packages from duplicate loading by a Hadoop configuration class loader, include them in the ignored.classes property within the plugin.properties file. This is necessary when logging libraries expect a single class shared by all class loaders, as with Apache Commons Logging for example
