liuxian closed SPARK-26264.
---------------------------
> It is better to add @transient to field 'locs' for class `ResultTask`.
> -----------------------------------------------------------------------
>
> Key: SPARK-26264
> URL: https://issues.apache.org/jira/browse/SPARK-26264
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: liuxian
> Priority: Minor
>
> The field 'locs' is only used in driver side for class `ResultTask`, so it
> is not needed to serialize when sending the `ResultTask` to executor.
> Although it's not very big, it's very frequent, so we can add` transient` for
> it like `ShuffleMapTask`
