Hadoop consists of several components. Components like HDFS and HBase are quite suitable for "interactive" solutions (as in: I usually get an answer within 0.x seconds). If you really need "realtime" (as in: I want a guarantee that I have an answer within 0.x seconds) the answer is: No, HDFS/HBase cannot guarantee that. Other components like MapReduce (and Hive which run on top of MapReduce) are purely batch oriented. -- Met vriendelijke groeten, Niels Basjes
