>                 Key: SPARK-15815
>                 URL: https://issues.apache.org/jira/browse/SPARK-15815
>             Project: Spark
>          Issue Type: Bug
>          Components: Scheduler, Spark Core
>    Affects Versions: 1.6.1
>            Reporter: SuYan
>            Priority: Minor
>
> Enable BlacklistExecutor with some time large than 120s and enabled 
> DynamicAllocate with minExecutors = 0
> 1. Assume there only left 1 task running in Executor A, and other Executor 
> are all timeout.  
> 2. the task failed, so task will not scheduled in current Executor A due to 
> enable blacklistTime.
> 3. For ExecutorAllocateManager, it always request targetNumExecutor=1 
> executors, due to we already have executor A, so the oldTargetNumExecutor  == 
> targetNumExecutor = 1, so will never add more Executors...even if Executor A 
> was timeout.  it became endless request delta=0 executors.
