Sean Owen updated SPARK-8974:
-----------------------------
    Target Version/s:   (was: 1.4.0)
       Fix Version/s:     (was: 1.4.1)

[~KaiXinXIaoLei] I'd ask again that you read 
https://cwiki.apache.org/confluence/display/SPARK/Contributing+to+Spark  Your 
JIRA doesn't make sense: it can't be Fixed for 1.4.1 already, since there is no 
change here. It can't Target Version 1.4.0 which is already released

> The spark-dynamic-executor-allocation may be not supported

> In yarn-client mode and config option "spark.dynamicAllocation.enabled " is 
> true, when the state of ApplicationMaster is dead or disconnected, if the 
> tasks are submitted  before new ApplicationMaster start. The thread of 
> spark-dynamic-executor-allocation will throw exception, When 
> ApplicationMaster is running and not tasks are running, the number of 
> executor is not zero. So feture of dynamicAllocation are not  supported.
