### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [x] I have searched in the [issues](https://github.com/apache/incubator-uniffle/issues?q=is%3Aissue) and found no similar issues. ### Describe the bug In the doReportShuffleResult method of the ShuffleServerGrpcClient, there may be a timeout situation, but the ShuffleServer end will also receive the corresponding block metadata. The final operation is the Roaring64NavigableMap object in the partitionsToBlockIds of the ShuffleServer. At this point, the Roaring64NavigableMap object is only locked on the write side. If during the retry process, both reading and writing occur simultaneously, This leads to the loss of block metadata when reading, ultimately resulting in data loss. ### Affects Version(s) 0.11.0 ### Uniffle Server Log Output ```logtalk ``` ### Uniffle Engine Log Output ```logtalk ``` ### Uniffle Server Configurations ```yaml ``` ### Uniffle Engine Configurations ```yaml ``` ### Additional context _No response_ ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
