> Method looks like :

> private ZoneId extractWriterTimezoneFromMetadata(JobConf job, FileSplit split,
> GenericDatumReader<GenericRecord> gdr) throws IOException {
> if (job == null || gdr == null || split == null || split.getPath() == null) {
> return null;
> }
> try {
> DataFileReader<GenericRecord> dataFileReader =
> new DataFileReader<GenericRecord>(new FsInput(split.getPath(), job), gdr);
> [...return...]
> }
> } catch (IOException e) {
> // Can't access metadata, carry on.
