### What changes were proposed in this pull request? When `ShuffleBlockFetcherIterator` initialize, call `fetchUpToMaxBytes` then call `fetchAllHostLocalBlocks`, <img width="2190" height="1656" alt="image" src="https://github.com/user-attachments/assets/829ab991-a9d2-4216-9b71-6ccc11681083"; /> but `fetchAllHostLocalBlocks` requests always need to wait `fetchUpToMaxBytes`'s open block RPC request return then can return. if open block request return slow, fetchRemoteWaitTime metrics difference is very large . ### Why are the changes needed? Make shuffle fetch wait time request time more accurate. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
