## *Tips* - *Thank you very much for contributing to Apache Hudi.* - *Please review https://hudi.apache.org/contributing.html before opening a pull request.* ## What is the purpose of the pull request JIRA https://issues.apache.org/jira/browse/HUDI-1376 When updating a Hudi table through Spark datasource, it will use the schema of the input dataframe as the schema stored in the commit files. Thus, when upserted with rows containing metadata columns, the upsert commit file will store the metadata columns schema in the commit file which is unnecessary for common cases. And also this will bring an issue for the reading of bootstrap table. Since the schema of metadata columns is always the same, we should remove the schema of metadata columns in the commit file for any insert/upsert/... action. ## Brief change log Remove the avro schema of metadata columns when writing to commit files *(for example:)* - *Modify AnnotationLocation checkstyle rule in checkstyle.xml* ## Verify this pull request This change added tests and can be verified as follows: - Add a test case to cover this change. ## Committer checklist - [x] Has a corresponding JIRA in PR title & commit - [x] Commit message is descriptive of the change - [ ] CI is green - [ ] Necessary doc changes done or have another open PR - [ ] For large changes, please consider breaking it into sub-tasks under an umbrella JIRA. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
