------------------------------------
Summary: Schema changes in HIVE-12274 for Oracle may not work for
upgrade
Key: HIVE-17333
URL: https://issues.apache.org/jira/browse/HIVE-17333
Project: Hive
Issue Type: Bug
Components: Metastore
Affects Versions: 3.0.0
Reporter: Naveen Gangam
Assignee: Naveen Gangam
According to
https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1770086700346491686
(reported in HIVE-12274)
The alter table command to change the column datatype from {{VARCHAR}} to
{{CLOB}} may not work. So the correct way to accomplish this is to add a new
temp column, copy the value from the current column, drop the current column
and rename the new column to old column.
