[jira] [Resolved] (ACCUMULO-1817) Use Hadoop Metrics2

["Josh Elser (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ACCUMULO-1817?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Josh Elser resolved ACCUMULO-1817.
----------------------------------
    Resolution: Fixed

We now support both the existing (henceforth referred to as "legacy") JMX endpoints as well as Metrics2-handled endpoints (by default).

Verified that JMX entries are still being populated for both variants (current and legacy) and also verified Graphite sink for current metrics (did not verify ganglia).

> We currently expose JMX and it's possible (with external code) to bridge the JMX to solutions like Ganglia. It would be ideal if the integration were native and pluggable.
> Turns out that Hadoop (hdfs, mapred) and HBase has "direct" metrics reporting to Ganglia through some nice code provided in Hadoop.
> Look into the GangliaContext to see if we can implement Ganglia metrics reporting by Accumulo configuration alone.
