Hello
I am working on a model in which I have to manage question and their answers. I create two columns, one in which question is to be store and other its answer. Now people will ask question, so when a new question come I want to execute map reduce job which find is same kind of question is already exist or not. If same question is asked then with map reduce I will find similar question that exist and provide answer to him that is already there with it. Also I want to append it with the similar question that is already their in my table. If question is different then I will store it in different row and its answer will be given by some expert and be stored. I know Hadoop HBase have property write once read many times. So I can't append it. I have two other options. 1. Manage new similar question with help of timestamp. 2. As a new similar question come I make new column qualifier and store it in same row. Please suggest that which approach should I follow and also that help in my map reduce operation where I have to analyze similarity of new question with every question that already exist. Also if some other approach can help me please suggest me. Regards Aseem Puri
