> when calling:
> PipesResult pipesResult = pipesClient.process(new 
> FetchEmitTuple(request.getFetchKey(),
>                     new FetchKey(fetcher.getName(), request.getFetchKey()), 
> new EmitKey(), tikaMetadata, HandlerConfig.DEFAULT_HANDLER_CONFIG, 
> FetchEmitTuple.ON_PARSE_EXCEPTION.SKIP));
> the tikaMetadata is not present in the fetch data when the fetch method is 
> called.
>  
> It's OK through this part: 
>             UnsynchronizedByteArrayOutputStream bos = 
> UnsynchronizedByteArrayOutputStream.builder().get();
>             try (ObjectOutputStream objectOutputStream = new 
> ObjectOutputStream(bos))
> {                 objectOutputStream.writeObject(t);             }
>             byte[] bytes = bos.toByteArray();
>             output.write(CALL.getByte());
>             output.writeInt(bytes.length);
>             output.write(bytes);
>             output.flush();
>  
> i verified the bytes have the expected metadata from that point.
>  
> UPDATE: found issue
>  
> org.apache.tika.pipes.PipesServer#parseFromTuple
>  
> is using a new Metadata when it should only use empty metadata if fetch tuple 
> metadata is null.
