> I noticed sometimes the testcase for SPARK-31485 fails.
> The reason should be related to the locality wait. 
> If the scheduler waits for a resource offer which meets the preferred 
> location for a task until the time-limit of process-local but no resource can 
> be offered for the locality level, the scheduler will give up the preferred 
> location. In this case, such task can be assigned to off-preferred location.
> The testcase for SPARK-31485, there are two tasks and only one task is 
> supposed to be assigned at one schedule round but both two tasks can be 
> assigned in that situation mentioned above and the testcase will fail.
