How to handle error path with easy-batch about vocadb-video-downloader-new HOT 1 CLOSED

Answer:

• create an ErrRecorder class to handle writing errors to the /err path
  • ErrRecorder class can not be a subclass of Listener because we want to write any thing possible to error json file
• use Listener to handle exp in intermediate processing
  • which basically direct the writing process to ErrRecorder
• let writer class includes the bean of ErrRecorder, this requires us to handle exp code flow by ourself
  • we can't use WriterListener because it takes the whole Batch<> as an argument
• no listener for reader class, just go hard failure
