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.
