FMX opened a new pull request, #2986: URL: https://github.com/apache/celeborn/pull/2986
### What changes were proposed in this pull request? Fix the issue of losing the primary location when parsing `GetReducerFileGroupResponse` from `LifecycleManager`. ### Why are the changes needed? In previous optimizations, I introduced packed partition locations to reduce the size of RPC calls, based on the assumption that primary partition locations would always be available. However, in some test scenarios where data replication is enabled and workers are randomly terminated, the primary location may be lost while the replica location remains. This causes the replica locations to be ignored which will cause data loss. ### Does this PR introduce _any_ user-facing change? NO. ### How was this patch tested? GA and cluster. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
