------------------------------------

             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.
