## *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 *Add support for pre-commit validation hooks through hive/presto queries. We provide mechanism to read uncommitted data through InputFormat. If validation passes, we will promote the commit. Otherwise, rollback the commit. ## Brief change log * Add new consume mode: validate. In this consume mode, we allow reading dirty data. Users can run hive/presto queries, validate data and then commit/abort. Note that users also need to explicitly specify dirty commit time to use this API. (We can consider making this optional) * In the first version, only added support for COW tables and parquet format. If general approach looks good, i can extend support for other file formats/table types as a follow up. ## Verify this pull request This change added tests. ## Committer checklist - [ ] Has a corresponding JIRA in PR title & commit - [ ] 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.
