Hi Kiran,

In HBase the data is denormalized but at the core HBase is KeyValue based
database meant for lookups or queries that expect response in milliseconds.
OLAP i.e. data warehouse usually involves heavy data crunching. HBase is
not really intended for heavy data crunching. If you want to just store
denoramlized data and do simple queries then HBase is good. For OLAP kind
of stuff, you can make HBase work but IMO you will be better off using Hive
for  data warehousing.

HTH,
Anil Gupta
