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.
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 plugin.properties 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 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.
