Summary: Fix schema evolution gaps for FG reader
Key: HUDI-9561
URL: https://issues.apache.org/jira/browse/HUDI-9561
Project: Apache Hudi
Issue Type: Improvement
Reporter: Lin Liu
Assignee: Lokesh Jain
Fix For: 1.1.0
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
