> {{org.apache.hadoop.mapred.RecordReader}} has a close method; but doesn't implement closeable;
it would be nice to add that - it would enable to use:
> {code}
> try( org.apache.hadoop.mapred.RecordReader<?, ?> recordReader = inputFormat.getRecordReader(...
)   ){
>  [...]
> }
> {code}
> ...supporting t-w-r makes it easier to throw exceptions more safely
