Apache Spark reassigned SPARK-26363:
------------------------------------
Assignee: Apache Spark
> Remove redundant field `executorLogs` in TaskData
> -------------------------------------------------
>
> Key: SPARK-26363
> URL: https://issues.apache.org/jira/browse/SPARK-26363
> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> Affects Versions: 3.0.0
> Reporter: Gengliang Wang
> Assignee: Apache Spark
> Priority: Major
>
> In https://github.com/apache/spark/pull/21688, a new filed `executorLogs` is
> added to `TaskData` in `api.scala`:
> 1. The field should not belong to `TaskData` (from the meaning of wording).
> 2. This is redundant with ExecutorSummary.
> 3. For each row in the task table, the executor log value is lookup in KV
> store every time, which can be avoided for better performance in large scale.
> This PR propose to reuse the executor details of request "/allexecutors" , so
> that we can have a cleaner api data structure, and redundant KV store queries
> are avoided.
