> Currently I'm working on export HLog to another FileSystem, then I found the 
> code of WALCellCodec and  its related classes is not that clean. And there 
> are several TODOs. Thus I tried to refactor the code based one these TODOs. 
> e.g.
> {code}
>   // TODO: it sucks that compression context is in WAL.Entry. It'd be nice if 
> it was here.
>   //       Dictionary could be gotten by enum; initially, based on enum, 
> context would create
>   //       an array of dictionaries.
>   static class BaosAndCompressor extends ByteArrayOutputStream implements 
> ByteStringCompressor {
>     public ByteString toByteString() {
>       // We need this copy to create the ByteString as the byte[] 'buf' is 
> not immutable. We reuse
>       // them.
>       return ByteString.copyFrom(this.buf, 0, this.count);
>     }
> {code}
