      • hasWriterVersion

        boolean hasWriterVersion()
         The version of the writer that wrote the file. This number is
 updated when we make fixes or large changes to the writer so that
 readers can detect whether a given bug is present in the data.
 Only the Java ORC writer may use values under 6 (or missing) so that
 readers that predate ORC-202 treat the new writers correctly. Each
 writer should assign their own sequence of versions starting from 6.
 Version of the ORC Java writer:
   0 = original
   1 = HIVE-8732 fixed (fixed stripe/file maximum statistics &
                        string statistics use utf8 for min/max)
   2 = HIVE-4243 fixed (use real column names from Hive tables)
   3 = HIVE-12055 added (vectorized writer implementation)
   4 = HIVE-13083 fixed (decimals write present stream correctly)
   5 = ORC-101 fixed (bloom filters use utf8 consistently)
   6 = ORC-135 fixed (timestamp statistics use utc)
   7 = ORC-517 fixed (decimal64 min/max incorrect)
   8 = ORC-203 added (trim very long string statistics)
   9 = ORC-14 added (column encryption)
 Version of the ORC C++ writer:
   6 = original
 Version of the Presto writer:
   6 = original
 Version of the Scritchley Go writer:
   6 = original
 Version of the Trino writer:
   6 = original
        optional uint32 writerVersion = 6;
        Returns:
        Whether the writerVersion field is set.
