Subject [jira] Created: (HADOOP-218) Inefficient calls to get configuration values in TaskInprogress
Date Sun, 14 May 2006 22:09:05 GMT
Inefficient calls to get configuration values in TaskInprogress
---------------------------------------------------------------

         Key: HADOOP-218
         URL: http://issues.apache.org/jira/browse/HADOOP-218
     Project: Hadoop
        Type: Improvement

  Components: mapred  
    Reporter: Mahadev konar
 Assigned to: Mahadev konar 
    Priority: Minor


Each time a pollforNewTask in called on the JobTracker, the taskinprogress makes a call to
hasSpeculativeTask() which current does a conf.getSpeculativeExecution() each time its called.
The fix would be to store it in the TaskInProgress as soon as it is created and make only
a single call to conf.getSpeculativeExecution().
