--------------------------------
Summary: Locality Level is ANY on "Details for Stage" WebUI page
Key: SPARK-10149
URL: https://issues.apache.org/jira/browse/SPARK-10149
Project: Spark
Issue Type: Bug
Components: Spark Core, Web UI
Affects Versions: 1.4.1
Reporter: Yun Zhao
Locality Level is ANY on "Details for Stage" WebUI page
When a sc.textFile(XX) program is running, Locality Level is ANY which should
be NODE_LOCAL on stage 0.
org.apache.spark.scheduler.TaskSetManager
// Check for node-local tasks
if (TaskLocality.isAllowed(locality, TaskLocality.NODE_LOCAL)) {
for (index <- speculatableTasks if canRunOnHost(index)) {
val locations = tasks(index).preferredLocations.map(_.host)
if (locations.contains(host)) {
speculatableTasks -= index
return Some((index, TaskLocality.NODE_LOCAL))
}
}
}
The variable "locations" is hostname of HDFS split, which is from
InetAddress.getHostName.
The variable "host" is ip of Executor, which is from
InetAddress.getLocalHost.getHostAddress.
org.apache.spark.deploy.worker.WorkerArguments
var host = Utils.localHostName()
