> Project: IMPALA
> Issue Type: Sub-task
> Components: Distributed Exec
> Reporter: Tim Armstrong
> Assignee: Michael Ho
> Priority: Major
> Labels: resource-management

> We should reserve memory for any required exchange buffers and allocate them
> from the buffer pool. This would ensure that queries won't allocate exchange
> buffers that will push them over the memory limit
