### 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 feature

I found many tasks failed on the shuffle writer or reader initialization due to network hang or other problems, but now these errors haven't exposed to the uniffle event logs.

Based on above, we should involve these initialization failures exposed into the event logs.

Research direction

Start by tracing shuffle writer and reader initialization and the existing Uniffle event-log path, then identify where network hangs and other initialization failures are currently lost. Done means those initialization failure reasons are exposed in the event logs for both components, with behavior verified using the project's relevant tests.
