Sergey Shelukhin commented on HIVE-13653:
-----------------------------------------
Deriving IO memory is not a good idea as it depends on user preferences and
executor size and count.
Arena size is already derived.
Min allocation/max allocation are assumed to be pretty much hardcoded, there's
rarely reason to change them (min allocation apparently impacts perf a bit so
maybe some people will lower it). The reason we saw issues is that people were
setting cache size to small values, like 4Mb, the MIN_SIZE prevents that now,
so the only way they can be in error is if someone configures them manually.
> improve config error messages for LLAP cache size/etc
