Szehon Ho updated HIVE-10761:
-----------------------------
Component/s: Diagnosability
> Create codahale-based metrics system for Hive
> ---------------------------------------------
>
> Key: HIVE-10761
> URL: https://issues.apache.org/jira/browse/HIVE-10761
> Project: Hive
> Issue Type: New Feature
> Components: Diagnosability
> Reporter: Szehon Ho
> Assignee: Szehon Ho
> Attachments: HIVE-10761.patch, hms-metrics.json
>
>
> 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.
