Tsz Wo Nicholas Sze commented on HDFS-7859:
-------------------------------------------
> ... We would persist the whole schema object ...
How can we be sure that the schema object format won't change?
Since we don't not yet support add/delete/update/rename schema operations, we
don't need to persist anything in NN at this moment. We will support some of
these schema operations down the road. We may persist schemas at that time.
Sound good?
