You are both making correct points, but FWIW HBase does not require use of 
Hadoop YARN or MapReduce. We do require HDFS of course. Some of the tools we 
ship are MapReduce applications but these are not core functions. We know of 
several large production use cases where the HBase(+HDFS) clusters are used as 
a data store backing online applications without colocated computation.
