Fix Version/s: Impala 3.2.0
> Order by docs incorrectly state that order by happens on one node

> https://impala.apache.org/docs/build/html/topics/impala_order_by.html
> "because the entire result set must be produced and transferred to one node
> before the sorting can happen." is incorrect. If there is an "ORDER BY"
> clause in a select block, then first data is sorted locally by each impala
> daemon, then streamed to the coordinator, which merges the sorted result sets.
