## Summary This PR aligns the `ContentFile` partition field JSON serialization in `ContentFileParser` with the REST spec, that specifies partition data as an ordered array of values. The REST spec uses an array of primitives to represent partitions, and that was discussed here in https://github.com/apache/iceberg/pull/9717#discussion_r1495010775 when the spec was designed. However, while testing it looks like `ContentFileParser` hasn't had the updates to reflect this yet and was using `SingleValueParser`, which produces a field ID map like `{"1000": 1}` instead of an array `[1]`. ## Testing **Serialize a partitioned data file:** ``` > ContentFileParser.toJson(dataFile, spec) {"spec-id":0,"content":"DATA","file-path":"data.parquet", "file-format":"PARQUET","partition":[1],"file-size-in-bytes":10, "record-count":1,"sort-order-id":0....} ``` **Unpartitioned table** ``` {"partition":[]} ``` **non array:** ``` > ContentFileParser.partitionFromJson({"partition": {"1000": 1}}, specs) java.lang.IllegalArgumentException: Invalid partition data for content file: non-array... ``` cc: @singhpk234 @amogh-jahagirdar -- This is an automated message from the Apache Git Service.
