No, we refer to it as "Max Memory" in our docs, and it can be set in 
fair-scheduler.xml in tags <maxResources>2500 mb</maxResources>. Please note 
that you can also set other resources there, e.g. <maxResources>128 mb, 1 
vcores</maxResources>. I think I'll just refer to it as "Max Memory", as this 
is what we use in our docs.
impala.admission-control.max-query-mem-limit is different, it is for setting a 
per-host max memory limit for queries.

Updated the message, but feel free to recommend a different one.
