[CARBONDATA-1490] Fixed memory allocation for carbon row Analysis: While creating carbon row the space for measures is assigned based on outputLength and not on measureCount which will tend to allocate more space than is actually needed. **outputLength = measureCount + ((noDictCount + complexCount) > 0 ? 1 : 0) + 1** When the table has 1 complex column then measureCount=0, noDictCount=0, complexCount=1 therefore, outputLength = 2 Even if there are no measure columns the measure object is created with 2 null values. Solution: Create measure object based on the measureCount.
