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

Including Additional Class Paths or Libraries

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

Exclude Classes or Packages

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