> {code}
> The PerfLogger instance is configurable via {{hive.exec.perf.logger}} (HIVE-11891) but
the requirement to extend from {{PerfLogger}} cannot be met since HIVE-11149 as the ctor is
private. Also useful methods in PerfLogger are also private. I tried to extend PerfLogger
for my needs and realized that, as is, the configurability is not usable. At the very least
the PerfLogger should make all private members {{protected}}, better the requirement should
be an interface not a class.
