Subject [jira] Created: (HADOOP-4623) Running tasks are not maintained by JobInProgress if speculation is off
Date Mon, 10 Nov 2008 08:00:44 GMT
Running tasks are not maintained by JobInProgress if speculation is off
-----------------------------------------------------------------------

                 Key: HADOOP-4623
                 URL: https://issues.apache.org/jira/browse/HADOOP-4623
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Amar Kamat


{{JobInProgress}} doesnt maintain any structure for running tasks if speculation is turned
_off_.  {{getRunningMapCache()}} in {{JobInProgress}} exposes the running map cache. This
api returns an empty {{Map}} if speculation turned off. 

_Usage_ :
{{CapicityScheduler}} requires a list of running tasks for both speculated and non-speculated
jobs. See HADOOP-4558 to see how this issue affects {{CapacityScheduler}}.
