> Update planner decisions to factor in mt_dop

> Key: IMPALA-9027
> URL: https://issues.apache.org/jira/browse/IMPALA-9027
> Project: IMPALA
> Issue Type: Sub-task
> Components: Frontend
> Reporter: Tim Armstrong
> Assignee: Tim Armstrong
> Priority: Major
> Fix For: Impala 3.4.0
>
>
> We need to make sure all decisions in the planner that currently use number
> of nodes use number of instances if appropriate.
> E.g.
> * HashJoinNode.computeNodeResourceProfile() has a TODO.
> * I think the broadcast/shuffle decision doesn't take into account mt_dop,
> which is wrong if we're broadcasting to multiple instances per fragment.
