Review Comment:
Yes. `ShuffleExchangeExec.createShuffleWriteProcessor` will call `getWriter`
of the shuffle manager internally (will be `CometShuffleManager` when comet
shuffle is enabled). `CometShuffleManager.getWriter` will initialize a
`CometNativeShuffleWriter` when shuffle type is `CometNativeShuffle`.
