> HIVE-18659 added hive.acid.version in the file footer.
> orcfiledump prints something like
> {noformat}
> User Metadata:
> hive.acid.key.index=1,536870912,1;
> hive.acid.stats=2,0,0
> hive.acid.version=
> {noformat}
> probably because
> {noformat}
> 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);
> }
> {noformat}
> use
> {{UTF8.encode())}} instead
