## *Tips* - *Thank you very much for contributing to Apache Hudi.* - *Please review https://hudi.apache.org/contribute/how-to-contribute before opening a pull request.* ## What is the purpose of the pull request Refactoring HoodieTestDataGenerator to provide for reproducible Builds: currently, `HoodieTestDataGenerator` relies on static state which make its state shared across all of the tests making data generation dependent on the order of execution. Instead we should properly abstract `HoodieTestDataGenerator` to hold all of the state w/in individual instances so that individual Tests can: 1. Create they own isolated instance (which won't be affected by other Tests) 2. Pass "seed" value to DataGenerator to init its PRNG w/ it, so that it always produces the same (pseudo-)random sequence (for a given seed) 3. Be certain that all of the data produced by DataGenerator will be 100% reproducible w/ the same seed (meaning that all of the DataGenerator operations w/in it only rely on such internal PRNG and don't rely on any external sources, such as `UUID.randomUUID()`, `System.currentTimeMillis()`, etc) ## Brief change log See above ## Verify this pull request This pull request is already covered by existing tests, such as *(please describe 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.
