> all the above lines throw the exception.
> The important thing is default values for the above properties are 0.05 and 0.8 
> But the getInt() Function takes only integer values, if not it takes only the integer part.
> In Hadoop io.sort.spill.percent,io.sort.record.percent,mapred.reduce.slowstart.completed.maps are expressed as Floating Point Numbers.
