Allen Wittenauer updated MAPREDUCE-5227: ---------------------------------------- Labels: BB2015-05-TBR (was: ) > JobTrackerMetricsSource and QueueMetrics should standardize naming rules > ------------------------------------------------------------------------ > > Key: MAPREDUCE-5227 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5227 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: mrv1 > Affects Versions: 1.1.3, 1.2.1 > Reporter: Tsuyoshi Ozawa > Assignee: Tsuyoshi Ozawa > Priority: Minor > Labels: BB2015-05-TBR > Attachments: MAPREDUCE-5227-1.1-branch.1.patch, > MAPREDUCE-5227-branch-1.1.patch, MAPREDUCE-5227.1.patch > > > JobTrackerMetricsSource and QueueMetrics provides users with some metrics, > but its naming rules( "jobs_running", "running_maps", "running_reduces") > sometimes confuses users. It should be standardized. > One concern is backward compatibility, so one idea is to share > MetricMutableGaugeInt object from old and new property name. > e.g. to share runningMaps from "running_maps" and "maps_running". -- This message was sent by Atlassian JIRA (v6.3.4#6332)
