I have a blog post on how to do this with NiFi using a Groovy script in the ExecuteScript (new in 0.5.0) processor using PDFBox instead of Tika:
http://funnifi.blogspot.com/2016/02/executescript-extract-text-metadata.html?m=1 Jython is also supported but can't yet use Java libraries (it uses Jython scripts/modules instead). The other languages (Groovy, Lua, JavaScript, JRuby) can use Java libraries like Tika and PDFBox.
