Alex Angelini updated SPARK-9745:
---------------------------------
Description:
When a job has only a single executor remaining and that executor dies (due to
something like an OOM), the application fails to notice that there are no
executors left and it hangs indefinitely.
This only happens when dynamic allocation is enabled.
The following images were taken from a hung application with no executors:
!logs_hung_job.png!
!am_hung_job.png!
!executors_hung_job.png!
!tasks_hung_job.png!
