Dear Wiki user,

The "TaskTable" page has been changed by ChiaHungLin:
https://wiki.apache.org/hama/TaskTable?action=diff&rev1=4&rev2=5

  
  == Job Task Relation ==
  
-  * Row: numBSPTasks
-  * Column: maxTaskAttempts
+ A TaskTable records tasks information. 
+  * The entire task table belongs to the same [[BSPJobID|BSPJobID]]. 
+  * A 2d array space is allocated with '''numBSPTasks''' row, and '''maxTaskAttempts''' is
configured to check if `attempt task' exceeds the upper bound. 
+  * Each row's first slot (ie Task[0]) is assigned with a task where 
+ {{{
+ TaskID's id: 1...N where N < numBSPTasks
+ TaskAttemptID' id: 1
+ }}}
+  * A task managed by the task table has attributes such that
+ {{{
+ {TaskID's id: 1...N where N < numBSPTasks, and the same row's id should equal.}
+ {TaskAttemptID's id: 1...M where M < maxTaskAttempts }
+ }}}

1, attemptId:2} || Task jobId:1, taskId: 1, attemptId:3 ||
