> As we all known, some performance metrics is important for enterprise applications. so we should support to collect metrics to JMX in Kylin.
> The method I have done is As shown below:
> 1. use `org.apache.hadoop.metrics2` as the metrics collection framework.
> 2. define MBean Class for the metrics that we need to collect.
> 3. update metrics in right place.
> The questions I have:
> 1. can I depend on `org.apache.hadoop.metrics2` directly?
> 2. how do you think about my method?
