----------------------------------------------

+1. I wonder why the file system counters are removed for some tests.

> Constants like 0.1 and 0.3 are differently boxed based on intermediate precision of the
compiler codepath.
> Disabling CBO produces 0.1BD constants which fail to box correctly to Double/Float.
> Enabling CBO fixes this issue, but cannot be applied all queries in Hive.
