Hi Community ,

In the last impala versions, impala is estimating the memory required for
the query, and in case the estimated memory required beyonds the configured
memory or  the configured memory per pool, impala is not submitting this
query, taking the fact that many times and specially running query on
tables without stats there is a huge difference between the estimated and
the actual memory used, the estimated can be 31 GB per node and the actual
use is 1 or 2 GB, that’s mean to submit a query I need at least 1.5 T
memory configured which I see it too much.

I’m curios to know if there is an option making this to configuration ( Un
submitting query if we he estimated memory required beyond the configured
memory) as an optional choice.

Such issue can block using impala dynamic resource pools.
