-----------------------------------------------------------------

i believe we are seeing this issue. it shows up in particular when pre-emption 
is turned on and we are using dynamic partition overwrite. pre-emption kills 
tasks, they get restarted, and then they fail again because the output 
directory already exists (so task throws FileAlreadyExistsException). as a 
result entire job fails.

so i dont think this is just a speculative execution issue. this is a general 
issue with dynamic partition overwrite not being able to recover from task 
failure.

see also SPARK-29302 which is same issue i believe.
