hbase
Just curious, does hbase require mapreduce? Basically, I have several
terabytes of data and I would like to query it similar to sql fashion.
Was wondering if mapreduce was required.

(changing to user hbase distlist instead of general hadoop)
Hive runs as MapReduce jobs. If you are looking for "quick" (i.e., non-MapReduce) access to tables, you need to use the HBase client (Get, Scan).

It seems with HIVE is a large latency. Is there anything else out there which has less latencies?

Mapreduce isn't required.
For your query, Hive would be a better fit.
