Subject [jira] [Commented] (HIVE-13480) Add hadoop2 metrics reporter for Codahale metrics
Date Thu, 14 Apr 2016 20:57:25 GMT


Sushanth Sowmyan commented on HIVE-13480:

[~elserj] : Thanks! Wanted to be sure that I was using your library correctly-ish. :)

[~szehon] - good point - I'll make a minor modification to add the version to the root pom,
and depend on the version variable here.

> Multiple other apache components allow sending metrics over to Hadoop2 metrics, which
allow for monitoring solutions like Ambari Metrics Server to work against that to show metrics
for components in one place. Our Codahale metrics works very well, so ideally, we would like
to bridge the two, to allow Codahale to add a Hadoop2 reporter that enables us to continue
to use Codahale metrics (i.e. not write another custom metrics impl) but report using Hadoop2.
> Apache Phoenix also had such a recent usecase and were in the process of adding in a
stub piece that allows this forwarding. We should use the same reporter to minimize redundancy
while pushing metrics to a centralized solution like Hadoop2 Metrics/AMS.
