Hadoop: Example process to generating a SequenceFi

问题:

Following Hadoop: how to access (many) photo images to be processed by map/reduce? question, where orangeoctopus provides a reasonable direction to load the image binaries and collect them into SequenceFiles to feed the mapper.

Think this could be useful for the others also, as a local java process or probably a hadoop job in case of vast amount image files, I created this separate question to look for the example for the implementation.

Thanks!

Hadoop: The Definitive Guide - Chapter 4 has some samples for reading/writing sequence files. Here is the code for the same. Go through the code and change it for the binary images as input for the sequence file.
