liyang commented on KYLIN-2721:
-------------------------------
Great to see this new initiative regarding metrics. I have a few questions.
- Kylin is already using {{org.apache.hadoop.metrics2}} in {{QueryMetrics}}.
How necessary moving to a new metrics framework?
- Assume we agree on moving to the new metrics framework, we will also refactor
the current {{QueryMetrics}} such that Kylin don't end up with two separate
metrics framework, right?
- Regarding collecting system metrics, like CPU, Memory etc, there are plenty
of tools already. I don't think Kylin should re-invent the wheel and do it
again. Does KYLIN-2724 mean something else, like integrate with those existing
tools?
- Could you elaborate more on the system cube?
Thanks!
