Subject [jira] [Created] (MAPREDUCE-6972) enable try-with-resources for RecordReader
Date Fri, 29 Sep 2017 07:29:00 GMT
Zoltan Haindrich created MAPREDUCE-6972:

             Summary: enable try-with-resources for RecordReader
                 Key: MAPREDUCE-6972
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6972
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Zoltan Haindrich

{{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:

try( org.apache.hadoop.mapred.RecordReader<?, ?> recordReader = inputFormat.getRecordReader(...
)   ){

...supporting t-w-r makes it easier to throw exceptions more safely
