Class MRScriptState

java.lang.Object
  org.apache.pig.tools.pigstats.ScriptState
      org.apache.pig.tools.pigstats.mapreduce.MRScriptState

public class MRScriptState
extends ScriptState

ScriptStates encapsulates settings for a Pig script that runs on a hadoop cluster. These settings are added to all MR jobs spawned by the script and in turn are persisted in the hadoop job xml. With the properties already in the job xml, users who want to know the relations between the script and MR jobs can derive them from the job xmls.
