> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, SQL
> Affects Versions: 3.4.0
> Reporter: Yang Jie
> Priority: Trivial
>
> Some code in Spark constructing ranges of collection indices manually as follows:
>
> {code:java}
> for (i <- 0 until shuffledOffers.size) {
> val execId = shuffledOffers(i).executorId
> val host = shuffledOffers(i).host
> val taskSetRpID = taskSet.taskSet.resourceProfileId {code}
> can use `shuffledOffers.indices` instead of `0 until shuffledOffers.size`
