> If the output directory is deleted then subsequent tasks should fail. Instead they blindly
create the missing parent directories, leading the job to be "succesful" despite potentially
missing almost all of the output. Task attempts should fail if the parent app attempt directory
is missing when they go to create their task attempt directory.
