[jira] [Created] (SPARK-14626) Simplify accumulators and task
metrics
Reynold Xin created SPARK-14626:
-----------------------------------
Summary: Simplify accumulators and task metrics
Key: SPARK-14626
URL: https://issues.apache.org/jira/browse/SPARK-14626
Project: Spark
Issue Type: Improvement
Components: Spark Core
Reporter: Reynold Xin
Assignee: Reynold Xin
The goal of the ticket is to simplify both the external interface and the internal implementation for accumulators and metrics. They are unnecessarily convoluted and we should be able to simplify them quite a bit.
This is an umbrella ticket and I will iteratively create new tasks as my investigation goes on. However, at a high level, I'd would like to create better abstractions for internal implementations, as well as creating a simplified accumulator v2 external interface that doesn't involve a complex type hierarchy.
