unable to fetch data from Hbase based on query parameters

[Monica Shiralkar]

How to get data from hbase? I have a table with empId,name,startDate,endDate and other columns.Now I want to get data from hbase table based upon empId,statDate and endDate.In normal SQL i will do this like..'select * from tableName where empId=val and date>=startDate and date<=endDate.

but how to do this in HBase as it stored data as key value pairs(key is empId)

thanks.
