> Support alter table change/replace/add columns for existing partitions

> Key: HIVE-7971
> URL: https://issues.apache.org/jira/browse/HIVE-7971
> Project: Hive
> Issue Type: Bug

>
> ALTER TABLE CHANGE COLUMN is allowed for tables, but not for partitions. Same
> for add/replace columns.
> Allowing this for partitions can be useful in some cases. For example, one
> user has tables with Hive 0.12 Decimal columns, which do not specify
> precision/scale. To be able to properly read the decimal values from the
> existing partitions, the column types in the partitions need to be changed to
> decimal types with precision/scale.
