### Search before asking - [X] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Paimon version 0.9 ### Compute Engine spark3.5.1 ### Minimal reproduce step 1. Spark generates a dataset where the chronic_list column is of type List<Integer> 2. Call dataset.show(), empty array display [] 3. But when I call dataset.write().mode(SaveMode.Append).format("paimon").save(path) to a piamon table, the query shows [null] ### What doesn't meet your expectations? 空数组应该是[]而不是[null] ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
