Hi rmetzger,
I've got a question: what if yarn.defaultNumberOfTaskManagers is set to a
invalid value, say -2? Should users have to supply the -n argument?
I was thinking this behavior may be appropriate:
If yarn.defaultNumberOfTaskManagers < 1 (not set or invalide value): users
have to supply the -n argument.
else if the user specified -n, the value of -n will have priority.
else, yarn.defaultNumberOfTaskManagers value will be used by default.
What do you think?
