| 111 | <P> |
---|
| 112 | TaskID represents the immutable and unique identifier for |
---|
| 113 | a Map or Reduce Task. Each TaskID encompasses multiple attempts made to |
---|
| 114 | execute the Map or Reduce Task, each of which are uniquely indentified by |
---|
| 115 | their TaskAttemptID. |
---|
| 116 | |
---|
| 117 | TaskID consists of 3 parts. First part is the <A HREF="../../../../org/apache/hadoop/mapreduce/JobID.html" title="class in org.apache.hadoop.mapreduce"><CODE>JobID</CODE></A>, that this |
---|
| 118 | TaskInProgress belongs to. Second part of the TaskID is either 'm' or 'r' |
---|
| 119 | representing whether the task is a map task or a reduce task. |
---|
| 120 | And the third part is the task number. <br> |
---|
| 121 | An example TaskID is : |
---|
| 122 | <code>task_200707121733_0003_m_000005</code> , which represents the |
---|
| 123 | fifth map task in the third job running at the jobtracker |
---|
| 124 | started at <code>200707121733</code>. |
---|
| 125 | <p> |
---|
| 126 | Applications should never construct or parse TaskID strings |
---|
| 127 | , but rather use appropriate constructors or <A HREF="../../../../org/apache/hadoop/mapreduce/TaskID.html#forName(java.lang.String)"><CODE>forName(String)</CODE></A> |
