Description

It would be convenient if, when starting up an Impala daemon in a container, it could automatically configure its own memory limit to the right value so that queries won't be overadmitted. It should sniff out the memory limit for the container (if there is one set).

E.g. see what Java did https://www.opsian.com/blog/java-on-docker/
