Is it is standard to do package version in the package name for Hadoop? I prefer to have the code in *org.apache.hadoop.metrics* to avoid package version in the package name. Otherwise +1 on the patch. > Overhaul metrics framework > -------------------------- > > Key: HADOOP-6728 > URL: https://issues.apache.org/jira/browse/HADOOP-6728 > Project: Hadoop Common > Issue Type: Improvement > Affects Versions: 0.20.2 > Reporter: Luke Lu > Assignee: Luke Lu > Fix For: 0.22.0 > > Attachments: hadoop-6728-y20.104.patch, metrics1-flow.png, metrics2-builder-r2.png, metrics2-builder.png, metrics2-flow.png, metrics2-mutable-r2.png, metrics2-mutable.png, metrics2-record-r2.png, metrics2-record.png, metrics2-uml-r2.png, metrics2-uml.png > > > Per discussions with Arun, Chris, Hong and Rajiv, et al, we concluded that the current metrics framework needs an overhaul to: > * Allow multiple plugins for different monitoring systems simultaneously (see also: HADOOP-6508). > * Refresh metrics plugin config without server restart. > ** Including filtering of metrics per plugin. > * Support metrics schema for plugins. > The jira will be resolved when core hadoop components (hdfs, mapreduce) are updated to use the new framework . Updates to external components that use the existing metrics framework will be tracked by different issues. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
