Class DrillApplicationMaster

org.apache.drill.yarn.appMaster.DrillApplicationMaster

public class DrillApplicationMaster
extends Object

Application Master for Drill. The name is visible when using the "jps" command and is chosen to make sense on a busy YARN node.

To debug this AM use the customized unmanaged AM launcher in this jar. (The "stock" YARN version does not give you time to attach the debugger.)
