Description

HIVE-18659 added hive.acid.version in the file footer.
orcfiledump prints something like

User Metadata:
  hive.acid.key.index=1,536870912,1;
  hive.acid.stats=2,0,0
  hive.acid.version=

probably because

    public static void setAcidVersionInDataFile(Writer writer) {
      //so that we know which version wrote the file
      ByteBuffer bf = ByteBuffer.allocate(4).putInt(ORC_ACID_VERSION);
      bf.rewind(); //don't ask - some ByteBuffer weridness. w/o this, empty buffer is written
      writer.addUserMetadata(ACID_VERSION_KEY, bf);
    }

use
UTF8.encode()) instead
