Example 1
/**
 * Create bolt which will persist ticks to HDFS.
 */
private static HdfsBolt createHdfsBolt() {

  // Use "|" instead of "," for field delimiter:
  RecordFormat format = new DelimitedRecordFormat()
    .withFieldDelimiter("|");
  // sync the filesystem after every 1k tuples:
  SyncPolicy syncPolicy = new CountSyncPolicy(100);

  // Rotate files when they reach 5MB:
  FileRotationPolicy rotationPolicy = 
    new FileSizeRotationPolicy(5.0f, Units.MB);

  // Write records to <user>/stock-ticks/ directory in HDFS:
  FileNameFormat fileNameFormat = new DefaultFileNameFormat()
    .withPath("stock-ticks/");

  HdfsBolt hdfsBolt = new HdfsBolt()
    .withFsUrl("hdfs://localhost:8020")
