Thanks Mohammad,

I searched Hadoop file format, but only find sequence file format, so it is
why I have the confusion.

   1. Are these file formats built on top of sequence file format?
   2. Appreciate if you could kindly point me to the official documentation
   for the file formats.

regards,
Lin
