Review Comment:
> Maybe it is because we write sc/rollup job as AlterJobV2, this base class
not have `rollupBatchTask`/`schemaChangeBatchTask`
hi @BiteTheDDDDt is there a way to reproduce this bug。 AlterJobV2 is
abstract class，once created，it must be RollupJobV2 or SchemaChangeJobV2， so I
don't think we find the real cause.
