Yes, you are right. NotImplementedException should be thrown when we will
implement later.
I found a workaround to get the total volume of hbase table, that is using
the HDFS command ```hadoop fs -du```. This will be inefficient, but may be very
helpful for query planning. So, I think we need to implement this function
someday. What do you think?
