> When a user is running on vagrant or single node with low system memory, configurations are not sufficient to allocate containers for "default" 6 vsegs per node especially during HASH dist table query or external table query. 
> Stack advisor should adjust the config values to ensure service checks and queries (including Random tables, HASH dist tables, PXF ext tables) do not fail.
