> Key: HIVE-17713
> URL: https://issues.apache.org/jira/browse/HIVE-17713
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin
>
> 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
