> Impala has an internal notion of "required threads" to execute a fragment, e.g. the fragment execution thread and the first scanner thread. It's possible to compute the number of required threads per fragment instance based on the plan.
> We should include this in the resource profile and expose it in the explain plan. This could then be a step toward implementing something like IMPALA-6035.
