> SPARK should support delete jar feature
> This feature aims at solving below use case.
> Currently in spark add jar API supports to add the jar to executor and Driver 
> ClassPath at runtime, if there is any change in this jar definition there is 
> no way user can update the jar to executor and Driver classPath. User needs 
> to restart the application to solve this problem which is costly operation.
> After this JIRA fix user can use delete jar API to remove the jar from Driver 
> and Executor ClassPath without the need of restarting the  any spark 
> application.
