Akira Ajisaka commented on MAPREDUCE-6972:
------------------------------------------
Would you add {{@Override}} annotation to the close method? I'm +1 if that is
addressed.
> enable try-with-resources for RecordReader

> {{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
