Subject [jira] Updated: (HADOOP-218) Inefficient calls to get configuration values in TaskInprogress

     [ http://issues.apache.org/jira/browse/HADOOP-218?page=all ]

Mahadev konar updated HADOOP-218:

    Attachment: speculative.patch

Here is a patch, that gets the configuration value once and stores it in the TaskInProgress.

> 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().
