I am trying to convert PDF into text using Mapreduce. Please guide me for executing PDF's using Mapreduce.
If you know how to convert text to pdf without mapreduce (for example with python), you can then call the relevant (python) function from pig.
How to do this is described in the Pig UDF manual

Im using GBQ, I want to export the results of a query into CSV file.
The data is larger than 20M lines so Im using this option :
In my query results I have some text in french, that is being saved in bad encoding to CSV.
Is there a way to define the encoding on Saving step in GBQ ?
Thank you
You can write simple Python script (or another language that made you feel comfortable) to query and save the result by using Python code. So you can use any encoding you want to save your result to CSV file.
I am trying to convert pdf file to Excel using Django, please anyone can help me how to convert pdf to excel in format way. I am trying, but the format does not work properly and also how to creating a download link for excel file.
It is possible to convert pdf to xlxs file in format way in Django ..?
please help how to do.
Django is a web framework, so i suppose your question was that how you can do that in Python. You can use this python library to convert the pdf to excel or CSV

What would be the most efficient way to grab data from Excel/Google Sheets using Python(2.7)/Django and then transform that data into beautiful graphs, charts etc. just like in this mockup?
Best regards,
Daviddep
Use the google docs api/sdk to read the sheet, or save them as .csv.
Read the csv, convert them to json.
Send the json to a javascript library like d3.js to create beautiful graphs
http://d3js.org/
http://datamaps.github.io/
My C++ application generates a .csv file containing 10000 floats.
Now the requirement is that there should be a graph in the same file depicting those floats.
I understand that csv files cannot have graphs. So I have to switch to Excel
Assuming I can write data into columns in excel sheet can anybody tell me if there is any function that I can call in my C++ program which will plot the data in excel sheet?
I have seen some solutions based on Python, but I am exploring if it is possible from C++ only.
www.google.com/search?q=C%2B%2B+Excel+OLE
The MSDN documentation is also often useful.
Try this library SimpleXlsxWriter. It is possible to plot basic graphs on the separate sheet in the excel book. There are also some examples of using on the wiki page of the project
The library provides no external dependencies
This might be of use, especially the last chapter:
www.maths.manchester.ac.uk/~ahazel/EXCEL_C++.pdf
CSV is a graph format.
It stands for Comma Separated Value.
You can load this file into Excel.
It will also import into SQL, MYSQL use (PHPMyadmin for this).
SQL stands for Structured Query Language. MYSQL is web based.
Best wishes to you.

I have an xml document which contains embedded pdf documents in base64 format. I'm using xsl:fo to create a pdf view of the xml, however I have absolutely no idea how to display the embedded documents as part of the overall output using xsl. Could someone help here please. Apologies if this is a very simple question, however I'm brand new to XSL and cannot seem to find any example of this anywhere.
PDF documents are vector images in some sense, and thus can be embedded into PDF output of an XSL FO rendering engine -- so far the first page only.
RenderX XEP accepts data: as URI schema for embedded images, so a base64 encoded PDF file placed as a string to fo:external-graphic/#src should work fine:
src="url('data:application/pdf;base64,encodedpdffilegoeshere...')"
