Eli Levine commented on PHOENIX-1429:
-------------------------------------

Looking over the patch...

In MergeSortResultIterator you left the
{code}
if (iterators != null) {
    SQLCloseables.closeAll(iterators);
}
{code}
at the bottom of the *close()* method. Intentional? The same code is invoked in 
the *finally* block in the new code.

> Cancel queued threads when limit reached

> We currently spawn a thread per guidepost to process a query. For a full scan 
> with a LIMIT of 1, this is particularly inefficient, as once we get our one 
> row back, we no longer need to execute the other queued threads. We should 
> cancel those threads once the limit is reached.
