-----------------------------------

             Summary: TaskSchedulerImpl should decrease availableCpus by 
spark.task.cpus not 1
                 Key: SPARK-1525
                 URL: https://issues.apache.org/jira/browse/SPARK-1525
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
            Reporter: YanTang Zhai
            Priority: Minor


TaskSchedulerImpl decreases availableCpus by 1 in resourceOffers process always 
even though spark.task.cpus is more than 1, which will schedule more tasks to 
some node when spark.task.cpus is more than 1.
