---------------------------------

             Summary: Reading data from file:/// should be called NODE_LOCAL not PROCESS_LOCAL
                 Key: SPARK-3528
                 URL: https://issues.apache.org/jira/browse/SPARK-3528
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.1.0
            Reporter: Andrew Ash


Note that reading from {{file:///.../pom.xml}} is called a PROCESS_LOCAL task

There is an outstanding TODO in {{HadoopRDD.scala}} that may be related:

{noformat}
  override def getPreferredLocations(split: Partition): Seq[String] = {
    // TODO: Filtering out "localhost" in case of file:// URLs
    val hadoopSplit = split.asInstanceOf[HadoopPartition]
    hadoopSplit.inputSplit.value.getLocations.filter(_ != "localhost")
  }
