Rui Fan commented on FLINK-32663:
---------------------------------
Don't find the root cause, just updating some temporary info here.
This test is savepoint instead of checkpoint, and the savepoint doesn't support
unaligned checkpoint. We can see this test is _client.triggerSavepoint_[1], and
the java doc of RescalingITCase also writes `/** Test savepoint rescaling.
*/`[2].
Hope these infos are useful for other contributors, I will continue analyze it
as well.
