### 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 I specify the following conf. ``` # HDFS fallback strategy rss.server.hybrid.storage.fallback.strategy.class org.apache.uniffle.server.storage.LocalStorageManagerFallbackStrategy rss.server.hybrid.storage.manager.selector.class org.apache.uniffle.server.storage.hybrid.HugePartitionSensitiveStorageManagerSelector ``` For one shuffle-server, fallback to hadoop storage is invalid when local storage's all disks are in high watermark. Because once all disks are in high-watermark, it will return null in selectStorage, and because the retry time default value is 0 in `LocalStorageManagerFallbackStrategy`. So it won't be fallbacked and then the event will be discarded in `DefaultFlushEventHandler`. I will fix this using the following 2 steps 1. allow setting the negative value for `rss.server.hybrid.storage.fallback.max.fail.times` 2. optimize `DefaultFlushEventHandler` when encountering null storage for one flush event. ### Affects Version(s) master ### Uniffle Server Log Output _No response_ ### Uniffle Engine Log Output _No response_ ### Uniffle Server Configurations _No response_ ### Uniffle Engine Configurations _No response_ ### 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.
