>
> We tested schema evolution support from FG reader through three tests:
> CASE1: Two base files have different schemas.
> CASE2: One base files with multiple log files, and log files have different
> schemas.
> CASE3: One base file and one log file have different schemas.
> Using the above tests, we found that there are some failures for:
> # Adding nested column for Hive: CASE1, CASE2
> # Adding nested column for Java: CASE2
> # Type upgrade from int to long Hive: CASE2
> The PR for running tests: https://github.com/apache/hudi/pull/13443
