Description

The ability to set an "unlimited" process mem limit is unnecessary (since you can configure the process limit to be arbitrarily large) and causes some complications in the code. It is also not tested automatically. We should remove this support in 2.11 after we officially deprecate it in 2.10 (IMPALA-5652).
