Now, in `BaseFile`, there are some metrics, like `nullValueCounts`, `nanValueCounts` etc, they use `UnmodifiableMap`, resulting in flink serialization problems. For example, the `RewriteDataFilesAction` and streaming read function will failed,the issue is here(#2219 ). I checked some information and found that [spark has similar problems if using kryo.](https://stackoverflow.com/questions/46818293/how-to-set-unmodifiable-collection-serializer-of-kryo-in-spark-code), so I remove the `UnmodifiableMap`, and I tested that, the `RewriteDataFilesAction` will not throw exception. what do you think about this ? @rdblue ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
