Hi, I am a beginner to Hadoop and I am looking for some help in implementing the Mapper with an image as input. Is there any predefined Writable class for processing image? If so, how do I use it?
Also I have read somewhere that compressed formats cannot be processed in Hadoop. If this is true, am I making any sense in saying that the JPEG images (which are also compressed format) cannot be processed by Hadoop? Please correct me if I have misunderstood this concept. Thanks, -- Aravinth
