**Search before asking** - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. **Paimon version** master @ b0af45681 **Compute Engine** Spark (format table) **Minimal reproduce step** `CREATE TABLE t (id INT, name STRING) USING json TBLPROPERTIES ('lineSep'='|')`, then read or write it with the default `format-table.implementation=paimon`. `JsonOptions.LINE_DELIMITER` (`json.line-delimiter`) has no fallback key, so `JsonFileReader` and `JsonFormatWriter` use `\n`. `CsvOptions.LINE_DELIMITER` and `TextOptions.LINE_DELIMITER` already accept `lineSep` via `withFallbackKeys("lineSep")`. **What doesn't meet your expectations?** `lineSep` is Spark's JSON option name. The `engine` implementation honours it, but the default `paimon` implementation ignores it, so the same table reads and writes differently depending on the implementation. **Anything else?** Proposed fix: add `.withFallbackKeys("lineSep")` to `JsonOptions.LINE_DELIMITER`, same as #9170/#9565 did for CSV. **Are you willing to submit a PR?** - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
