Szehon Ho updated HIVE-10761:
-----------------------------
    Description: 
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.

As part of this change, Hive's JVMPauseMonitor (that was using Hadoop's private 
one) is now hooked into the new metric framework to give pause time counts.

The existing metric subsystem will be kept and can be enabled if backward 
compatibility is desired.
