Description
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 the serde, since it's using the external schema to figure out what the columns are; leading to confusion and bugs. We should not allow such a modification for SerDes not in hive.serdes.using.metastore.for.schema
