 * Creates a specialized hadoop configuration for spydra. This configuration is
 * special in the sense that it configures hadoop tooling to be able to access GCS
 * for logs, history and is able to run a read-only job-history server (not moving
 * or deleting logs or history files). This configuration is dependent on client
 * and username due to how this information is stored in GCS.
 * @param clientId client id to generate configuration for
 * @param username username to generate configuration for
 * @param bucket   name of the bucket storing logs and history information
public static Configuration generateHadoopConfig(String clientId, String username,
    String bucket) {
  // We want minimalistic and clean options that are unlikely to collide with anything,
  // that's why not loading defaults
  Configuration cfg = new Configuration(false);

  if (logger.isDebugEnabled()) {
    logger.debug("Dumping generated config to be applied for log/history tools");

  return cfg;
