spuru9 opened a new pull request, #29156:
URL: https://github.com/apache/flink/pull/29156
## What is the purpose of the change
`CalcRestoreTest.testRestore` (the `calc-variant` program) fails on `master`
because the checked-in restore savepoint no longer deserializes:
```
java.io.InvalidClassException: org.apache.flink.types.variant.Variant; local
class incompatible: stream classdesc serialVersionUID = -1858271569023660977,
local class serialVersionUID = -3681789473927144047
```
`org.apache.flink.types.variant.Variant` is a `Serializable` interface
without an explicit `serialVersionUID`, so its auto-generated UID changes
whenever its declared method set changes. A new accessor method was added to
the interface after the `calc-variant` savepoint was last generated, which
shifted the UID and invalidated the checked-in savepoint.
This regenerates the `calc-variant` savepoint against the current `Variant`.
The compiled plan is unchanged.
## Brief change log
- Regenerate
`flink-table/flink-table-planner/src/test/resources/restore-tests/stream-exec-calc_1/calc-variant/savepoint/_metadata`.
## Verifying this change
- `CalcRestoreTest#testRestore` passes (10 tests, 0 failures / 0 errors)
with the regenerated savepoint.
- With the previous savepoint it fails on the `calc-variant` program with
the `InvalidClassException` above; regenerating resolves it.
