Description

The Folder code does the following

inputCycle = // extract the value of -input-cycle from args
..
// other inits and FileSystem operations
..
if (inputCycle <= 0) {
  LOG.error("You must have an input cycle length.");
  return NO_INPUT_CYCLE_LENGTH;
}

if (outputDuration <= 0) {
  outputDuration = 60L * 60L * TICKS_PER_SECOND;
}

if (inputCycle <= 0) {
  inputCycle = outputDuration;
}

There is no point in doing other initializations if -input-cycle is not provided
