>         Type: Improvement

>   Components: mapred

>     Priority: Minor
>      Fix For: 0.3.0
>  Attachments: speculative.patch
>
> 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().
