> 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
