> The getSplits methods of 
>   org.apache.hadoop.mapred.lib.CombineFileInputFormat 
> not work.
> ...mapred.lib.CombineFileInputFormat(0.20-style) is a proxy for ...mapreduce.lib.input.CombineFileInputFormat(0.21-style)
> The 0.21-style getSplits returns ArrayList<...mapreduce.lib.input.CombineFileSplit>
> and the 0.20-style delegation calls toArray(...mapred.InputSplit[])
> The ...mapreduce.lib.input.CombineFileSplit is based on ...mapreduce.InputSplit
> and ...mapred.InputSplit is a interface, not a super-class of ...mapreduce.InputSplit
