Review comment:
the `checkArgument` and the transformation could be put under the below `if`
clause, because it is strongly relevant with `if` condition.
Further, I think it is better to provide
`PartitionInfo.isLocationTo(consumerLocation)`, then we could make the check
and transformation hidden inside `PartitionInfo`, make `updateInputChannel` not
involve in more details.
