Shixiong Zhu resolved SPARK-18820.
----------------------------------
    Resolution: Duplicate

> Driver may send "LaunchTask" before executor receive "RegisteredExecutor"
> -------------------------------------------------------------------------
>
>                 Key: SPARK-18820
>                 URL: https://issues.apache.org/jira/browse/SPARK-18820
>             Project: Spark
>          Issue Type: Bug
>          Components: Scheduler
>    Affects Versions: 1.6.3
>         Environment: spark-1.6.3
>            Reporter: jin xing
>
> CoarseGrainedSchedulerBackend will update executorDataMap after receiving 
> "RegisterExecutor", thus task scheduler may assign tasks on to this executor;
> If LaunchTask arrives at CoarseGrainedExecutorBackend before 
> RegisteredExecutor, it will result in NullPointerException and executor 
> backend will exit;
> Is it a bug? If so can I make a pr? I think driver should send "LaunchTask" 
> after "RegisteredExecutor" is already received.
