------------------------------
Summary: all data fill in the same bucket because not check
INDEX_KEY_FIELD
Key: HUDI-4621
URL: https://issues.apache.org/jira/browse/HUDI-4621
Project: Apache Hudi
Issue Type: Bug
Components: flink, flink-sql
Reporter: wuwenchi
A table using bucket index has specified `INDEX_KEY_FIELD` other than the
primary key due to some errors. This operation will not report an error, but
all data will be inserted into the same bucket. Whether it is from the
definition of `INDEX_KEY_FIELD` or the final result, `INDEX_KEY_FIELD` should
be checked, otherwise bucket index is meaningless.
