Nishant Bangarwa commented on HIVE-19049:
-----------------------------------------
[~ashutoshc] Updated the patch to read old columns from storage descriptor
instead of metadata store. Also added a hook to the HiveMetaHook that can be
used by the StorageHandlers.
This hook is unused for druid storage handler as of now, since we do not
require to make any changes on druid side to add columns.
> Add support for Alter table add columns for Druid
