> Key: SPARK-20084
> URL: https://issues.apache.org/jira/browse/SPARK-20084
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, Web UI
> Affects Versions: 2.1.0
> Reporter: Ryan Blue
> Assignee: Apache Spark
>
> History files for large jobs can be hundreds of GB. These history files take too much space and create a backlog on the history server.
> Most of the size is from Accumulables in SparkListenerTaskEnd. The largest accumulable is internal.metrics.updatedBlockStatuses, which has a small update (the blocks that were changed) but a huge value (all known blocks). Nothing currently uses the accumulator value or update, so it is safe to remove it. Information for any block updated during a task is also recorded under Task Metrics / Updated Blocks.
