Examples of co.cask.cdap.common.conf.CConfiguration

co.cask.cdap.common.conf.CConfiguration
CConfiguration is an extension of the Hadoop Configuration class. By default, this class provides a empty configuration. To add a set of resources from an XML file, make sure the file is in the classpath and use config.addResource("my file name"); Note: This class will lazily load any configuration properties, therefore you will not be able to access them until you have called one of the getXXX methods at least once.

    if (data == null) {
      return CConfiguration.create();
    }


    ByteArrayInputStream bin = new ByteArrayInputStream(data);
    CConfiguration cConfiguration = CConfiguration.create();
    cConfiguration.clear();
    cConfiguration.addResource(bin);
    return cConfiguration;
