> Currently user will get a misleading error as
> org.apache.spark.sql.execution.streaming.state.StateSchemaNotCompatible if
> restarting query in the same checkpoint location and changing their stateful
> operator. We need to catches such errors and throws a new error with
> informative message.
> After physical planning, before execution phase, we will read from state
> metadata with the current operator id to fetch operator name of committed
> batch with the same operator id. If operator name does not match, throws the
> error.
