             Summary: Refactor HoodieTestDataGenerator to enable reproducible builds
                 Key: HUDI-3469
                 URL: https://issues.apache.org/jira/browse/HUDI-3469
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: Alexey Kudinkin


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
 # Create they own isolated instance (which won't be affected by other Tests)
 # Accept "seed" value for its PRNG so that it always produces the same random sequence (for a given seed)
 # All of the 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)
