   > can you provide more detail here.

   Our case is client mode. this error throw in driver side.
   So we can change to :
   
   1. client- mode, for this error we can have a retry.
   2. cluster-mode, since this ApplicationMaster running in the AM container, so we can just stop?
   
   > When you say its preempted, I assume that you mean this application was killed by the RM due to higher priority? If it was killed how can it stay alive.
   
   I mean client mode AM's container was preempted. Then RM can't find this attempt. Then client driver backend receive  ApplicationAttemptNotFoundException.
