Examples of org.apache.hadoop.mapred.DefaultTaskController

org.apache.hadoop.mapred.DefaultTaskController
The default implementation for controlling tasks. This class provides an implementation for launching and killing tasks that need to be run as the tasktracker itself. Hence, many of the initializing or cleanup methods are not required here.
NOTE: This class is internal only class and not intended for users!!
