Gopal V commented on HIVE-10761:
--------------------------------

Setting {{hive.server2.metrics.enabled=true}} seems to trigger another error

> There is a current Hive metrics system that hooks up to a JMX reporting, but 
> all its measurements, models are custom.
> This is to make another metrics system that will be based on Codahale (ie 
> yammer, dropwizard), which has the following advantage:
> * Well-defined metric model for frequently-needed metrics (ie JVM metrics)
> * Well-defined measurements for all metrics (ie max, mean, stddev, mean_rate, 
> etc), 
> * Built-in reporting frameworks like JMX, Console, Log, JSON webserver
> It is used for many projects, including several Apache projects like Oozie.  
> Overall, monitoring tools should find it easier to understand these common 
> metric, measurement, reporting models.
> The existing metric subsystem will be kept and can be enabled if backward 
> compatibility is desired.
