-------------------------------------
    Hadoop Flags: Reviewed
         Summary: Enable try-with-resources for RecordReader  (was: enable try-with-resources for RecordReader)
     Description: 
{{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
