[jira] [Created] (HUDI-3783) Fix HoodieTestTable harness to also properly validate Column Stats

             Summary: Fix HoodieTestTable harness to also properly validate Column Stats
                 Key: HUDI-3783
                 URL: https://issues.apache.org/jira/browse/HUDI-3783
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: Alexey Kudinkin


Currently `HoodieTestTable` generates invalid tables which prevent effective testing of the Column Stats Index:
 # It does write empty Parquet files, making impossible to construct proper ColStats records for these
 # It does set phony Commit Metadata omitting Schema (for aforementioned reasons), which breaks ColStats when trying to update records during Rollbacks/Cleanings as CS relies on TableSchemaResolver, which is not able to resolve schema for an invalid table
