I looked into the config files you linked here and it seems be for Dataflow ValidateRunner tests. I am not sure if we want to add these tests into that list, because - `HllCount` itself lives in a extension module that is outside of `:sdks:java:core`. If we want to run them on Dataflow post-commit tests we will need the `:runners:google-cloud-dataflow-java` module to depend on this extension module, which seems weird to me. - `HllCount` is just another aggregation transform built on top on the `Combine` transform, similar to `Sum`, `Mean`, or `Latest` (a more comprehensive list: https://beam.apache.org/documentation/transforms/java/overview/#aggregation). I checked the test list here https://builds.apache.org/job/beam_PostCommit_Java_ValidatesRunner_Dataflow/3162/testReport/org.apache.beam.sdk.transforms/ and non of those transforms are included (only fundamental transforms like `ParDo`, `Combine`, `GroupByKey` etc. are tested). However, I totally agree that we should have some tests against the target DataflowRunner for this feature. I am working on an integration test that tests not only `HllCount` works on Dataflow, but also it can interoperate with `BigQuery` with the same sketch format. There are some work need to be done, and I would like to put that integration test in a separate PR, to avoid blocking the review progress of this PR. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
