EdColeman opened a new pull request #1406: Backport gc metrics to 1.9.x to use hadoop metrics2.
URL: https://github.com/apache/accumulo/pull/1406
 
 
   This backport bring the gc metrics from master / 2.0 into the 1.9.x branch. The metrics
   can be enabled / disabled with GC_METRICS_ENABLED property (default false for 1.9.x)  The
   metrics changes include:
   
   - Publish current gc metrics to hadoop 2 metrics reporting system.
   - Add gc run counter that increments on each gc cycle run
   - Add metric to track time required for gc post op (compact, flush, none)
   
   Also Includes:
   
   - Move IT resource file for PR #1381 to correct directory so test passes
   in CI and on the command-line. Previously, it may have only worked in
   some IDEs, because of the way those IDEs put test resources on the class
   path.
