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

             Summary: PerfLogger is configurable, but not extensible
                 Key: HIVE-16612
                 URL: https://issues.apache.org/jira/browse/HIVE-16612
             Project: Hive
          Issue Type: Bug
          Components: Query Planning, Query Processor
            Reporter: Remus Rusanu
            Assignee: Remus Rusanu
            Priority: Minor


{code}
          result = (PerfLogger) ReflectionUtils.newInstance(conf.getClassByName(
            conf.getVar(HiveConf.ConfVars.HIVE_PERF_LOGGER)), conf);
{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.
