I want to read the PDF file using hadoop, how it is possible?
I only know that hadoop can process only txt files, so is there anyway to parse the PDF files to txt.
Give me some suggestion.
An easy way would be to create a SequenceFile to contain the PDF files. SequenceFile is a binary file format. You could make each record in the SequenceFile a PDF. To do this you would create a class derived from Writable which would contain the PDF and any metadata that you needed. Then you could use any java PDF library such as PDFBox to manipulate the PDFs.
