> This is kind of a followup from HIVE-11985
> When a SerDe uses an external schema (either embedded, or via a file link), it's not using the information stored in metastore for the columns. So, if the users modify table schema via add column and other such commands it won't have effect on serde, since it's using the external schema; leading to confusion and bugs. We should not allow such a modification for SerDes not in hive.serdes.using.metastore.for.schema
