Examples of org.apache.hadoop.mapreduce.TaskID

org.apache.hadoop.mapreduce.TaskID
TaskID represents the immutable and unique identifier for a Map or Reduce Task. Each TaskID encompasses multiple attempts made to execute the Map or Reduce Task, each of which are uniquely indentified by their TaskAttemptID. TaskID consists of 3 parts. First part is the {@link JobID}, that this TaskInProgress belongs to. Second part of the TaskID is either 'm' or 'r' representing whether the task is a map task or a reduce task. And the third part is the task number.
An example TaskID is : task_200707121733_0003_m_000005 , which represents the fifth map task in the third job running at the jobtracker started at 200707121733.
Applications should never construct or parse TaskID strings , but rather use appropriate constructors or {@link #forName(String)} method. @see JobID @see TaskAttemptID
