[jira] [Created] (HIVE-22062) WriteId is not updated for a partitioned ACID table when schema changes

             Summary: WriteId is not updated for a partitioned ACID table when schema changes
                 Key: HIVE-22062
                 URL: https://issues.apache.org/jira/browse/HIVE-22062
             Project: Hive
          Issue Type: Bug
            Reporter: Gabor Kaszab
            Assignee: Laszlo Kovari


Changing the schema (e.g. adding a new column) of a non-partitioned ACID table results in the table-level writeId being incremented.

However, if you do the same on a partitioned ACID table then neither the table-level nor the partition-level writeIds are updated. I would expect in this case to increment the table-level writeId to reflect that the table has been changed.
Note, that get_valid_write_ids() shows that the high watermark is incremented even though the writeId isn't.
