>  private ZoneId extractWriterTimezoneFromMetadata(JobConf job, FileSplit split,
>       GenericDatumReader<GenericRecord> gdr) throws IOException {
>     if (job == null || gdr == null || split == null || split.getPath() == null) {

>     try {
>       DataFileReader<GenericRecord> dataFileReader =
>           new DataFileReader<GenericRecord>(new FsInput(split.getPath(), job), gdr);
>       [...return...]
>       }
>     } catch (IOException e) {
>       // Can't access metadata, carry on.
>     }
>     return null;
>   }
> {code}
> The DataFileReader is never closed which can cause a memory leak. We need a try-with-resources here.
