I am seeing the MultiFileInputFormat and the MultipleOutputFormat
Input/Output formats for the Job configuration. How can I properly use
them? I had previously used the default Input and Output Format types,
which for my PDF concatenation project, merely reduced Hadoop to a
scheduler.
The idea is per directory, to concatenate all PDFs in said directory to
one PDF, and for this I'm using iText.
How can I use these Format types? What would be in my input into the
mapper and what would my InputKeyValue and OutputKeyValue classes be?
Thank you! I can't find documentation on these other than the Javadoc,
which doesn't help much.
