Description

Some code in Spark constructing ranges of collection indices manually as follows:

 

for (i <- 0 until shuffledOffers.size) {
      val execId = shuffledOffers(i).executorId
      val host = shuffledOffers(i).host
      val taskSetRpID = taskSet.taskSet.resourceProfileId 

can use `shuffledOffers.indices` instead of `0 until shuffledOffers.size`
