Hi Benedict As super user you should be able to get back the tags as ordinals and make sure you set the codec KeyValueCodecWithTags. But I am not sure if it is possible to do it from the hBase shell. Can you try from a java client ?
I did not do the hands on of late on this but I can do it if you face any difficulties and revert back if needed.
