>    Affects Versions: 1.6
>            Reporter: Alexey Kuznetsov
>            Priority: Major
> Ignite SQL engine use a mapreduce to execute query on cluster.
> Some node map queries over cluster and after they are completed and reduced 
> on initial node.
> In current implementation we measure duration on initial node and on all 
> nodes where two-step queries are executed, but only overall duration is 
> returned.
> We also need to return duration from all two-step queries.
