Example 61 with DataSetException

use of io.cdap.cdap.api.dataset.DataSetException in project cdap by cdapio.

the class FileSetDataset method determineBaseLocation.

/**
 * Generate the base location of the file set.
 * <ul>
 *   <li>If the properties do not contain a base path, generate one from the dataset name;</li>
 *   <li>If the base path is absolute, return a location relative to the root of the file system;</li>
 *   <li>Otherwise return a location relative to the data directory of the namespace.</li>
 * </ul>
 * This is package visible, because FileSetAdmin needs it, too.
 * TODO: Ideally, this should be done in configure(), but currently it cannot because of CDAP-1721
