## What changes were proposed in this pull request? Before this PR, we create accumulators at driver side(and register them) and send them to executor side, then we create `TaskMetrics` with these accumulators at executor side. After this PR, we will create `TaskMetrics` at driver side and send it to executor side, so that we can create accumulators inside `TaskMetrics` directly, which is cleaner. ## How was this patch tested? existing tests. Author: Wenchen Fan <wenchen@databricks.com> Closes #12472 from cloud-fan/acc. |
