Is it possible from the c# API to query data rather than returning a number of records?
#region Fetch result
HBaseOperation.FetchSize = 100;
HBaseResultSet result = HBaseOperation.ScanTable(tableName, con);
#endregion Fetch result
Like this from the samples in the big data managment studio
scan 'Customers',{ FILTER => "ValueFilter(=,'binaryprefix:Elizabeth Lincoln')"}
