113TaskAttemptID represents the immutable and unique identifier for
114 a task attempt. Each task attempt is one particular instance of a Map or
115 Reduce Task identified by its TaskID.
116 
117 TaskAttemptID consists of 2 parts. First part is the
118 <A HREF="../../../../org/apache/hadoop/mapred/TaskID.html" title="class in org.apache.hadoop.mapred"><CODE>TaskID</CODE></A>, that this TaskAttemptID belongs to.
119 Second part is the task attempt number. <br> 
120 An example TaskAttemptID is :
121 <code>attempt_200707121733_0003_m_000005_0</code> , which represents the
122 zeroth task attempt for the fifth map task in the third job
123 running at the jobtracker started at <code>200707121733</code>.
124 <p>
125 Applications should never construct or parse TaskAttemptID strings
126 , but rather use appropriate constructors or <A HREF="../../../../org/apache/hadoop/mapred/TaskAttemptID.html#forName(java.lang.String)"><CODE>forName(String)</CODE></A> 
127 method.
