Well, I see they are using .to_java_bytes to cast a string and pass it to
the put-method, that's ok. But I am having trouble calling
the inputStream.read method.
I tried this:
inFile = File.new("/home/roger/Downloads/test.jpg")
inputStream = FileInputStream.new(inFile)
length = inFile.length()
buffer = ""
inputStream.read(buffer)
But that won't work. It's probably more of a JRuby question than actually
an HBase issue...
