>             Project: Spark
>          Issue Type: Improvement

>    Affects Versions: 3.0.0

> 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`
